Built for Suleiman “The Magnificent” by the famous imperial architect Mimar Sinan in 1557, the Süleymaniye Mosque is modeled in part on the Hagia Sofia, and in part on a Byzantine basilica, in order to reflect the grandeur of the city’s past architectural monuments.

In 1660, the Süleymaniye Mosque was ravaged by fire and was restored by Mehmet IV. Unfortunately, that restoration work had changed the mosque into a baroque-style structure and ruined the original architecture. The mosque has undergone many restorations ever since. Today it is one of the most popular tourist sites in Istanbul.

The mosque complex consists of a caravanserai, an imaret (public kitchen), a madrassa (Islamic school), a hospital and a hammam (Turkish bath). The public kitchen was constructed to serve food to the poor. The gardens behind the mosque consist of Turbe (tombs) of the great Sultan Suleiman, his wife Roxelana, his mother Dilasub Saliham, his daughter Mihrimah and his sister Asiye. The tombs are fashioned on the Dome of the Rock in Jerusalem. The mosque is distinct from others as it contains the tomb of the great architect Sinan, designed by the occupant himself.

Why You Should Visit:
Great picturesque neighborhood, fewer tourists, sensational views of the city and quite a peaceful and solemn overall experience.

Tip:
To really enjoy the views, go down and find some restaurants on the rooftops of the buildings close to the mosque.
If you have trouble walking up and down, consider renting a (reliable) taxi cab or plan your ascent/descent accordingly.

One of the oldest markets in the world, the Grand Bazaar of Istanbul or the Kapalicarsi (“covered bazaar”) has more than 58 covered streets and more than 4,000 shops. Anywhere from a quarter to half a million visitors come here daily.

The Grand Bazaar was built from 1455 to 1461 and has been open ever since. It is famed for its exquisite Turkish jewelry, silver decoration pieces, spices, Turkish delights (famous Turkish sweets), pottery and carpet shops. Visitors can also find leather goods, gold and diamond jewelry, as well as clothing here in rich supply.

The bazaar is particularly famous for the “Turkish Evil Eye” – an amulet made of blue and white glass believed to ward off evil spirits. Almost every street here has an “evil eye” stall, with many variations of the amulet being sold to tourists.

Originally the bazaar contained bedestens, which are domed structures used for storage, and was enlarged during the 16th century. After a major earthquake in 1894, the bazaar went under major restoration. Today, it contains two hammams (Turkish baths), two mosques, four fountains, as well as many cafes and restaurants.

Why You Should Visit:
The bazaar's centuries-old history can still be seen from the countless frescoes on the many ceiling arches and ancient columns; however, the main charm lies in its chaotic organization. Every turn is full of unexpected surprises – you will never know what you're going to find! No purchase is necessary to join this festivity.

Tip:
If you are in need of Turkish Lira cash, this is an excellent place to exchange.
Be prepared to walk away if the seller does not agree with your asking price (or watch what happens next!).

The former Hippodrome of Constantinople, a circus arena where chariot races and other sporting events once marked the heyday of the Byzantine Empire, today got a new life in the form of Sultanahmet Meydanı (Sultan Ahmet Square) in the heart of modern-day Istanbul. Here, alongside a few surviving fragments of the ancient Hippodrome, you will find all the famous landmarks of the city, including the Blue Mosque, Hagia Sophia, Topkapi Palace Museum, Sultan Ahmed Mosque, Suleymaniye Mosque, Serpents column, the Museum of Turkish & Islamic Arts and many others. The Basilica Cistern is a mere 40m walk from the square and the Grand Bazaar is within a walking distance, too.

The square is very large and has lots of benches scattered around which is quite convenient for taking a break after long hours of sightseeing and/or for grabbing a quick bite from one of the food carts abound in the area selling a variety of breads, roasted corn and chestnuts, simit (Turkish pretzel) with or without chocolate cream, and plenty more. Along the tram line on both sides there are shops, restaurants and cafes offering generous selections of teas, coffee, Turkish Delights and gift packs.

As a gathering place, Sultanahmet is continuously bustling with tourists and locals alike, families enjoying the colorful artezian fountain, children running along the greenery between alleys, and the elderly folk basking in the brightness of life all around them. The square is also home to a large number of street cats and dogs who seem to be rather friendly and keep to themselves. The place is open to the elements and provides very little cover, so carrying an umbrella or raincoat, if rain is predicted, is highly recommended.

One of the most frequently visited and famous tourist spots in Istanbul, the Sultan Ahmed Mosque – popularly known as the “Blue Mosque” due to the blue tiles that adorn the walls of its interior – was built between 1609 and 1616 during the reign of Ahmed the First. It contains a tomb of the Sultan, a madrassah (religious school) and also a hospice. Despite being a very famous tourist attraction, it still functions as a mosque, and a call for prayer (azaan) still draws the faithful to its gates from far and wide. Usually accessible 24 hours a day, the mosque is not open for tourists during prayer time (which is approximately half an hour) five times a day, unless they are there to pray.

Built near the Hagia Sophia and surrounded by a popular tourist district, visitors to the mosque can enjoy several museums, cafes, restaurants and parks in the nearby vicinity. The mosque itself was originally built on the site of the ancient Byzantine Imperial Palace and Hippodrome and took nearly seven years to complete. This masterpiece of Ottoman architecture boasts many examples of Islamic Art and calligraphy that adorn its walls from the inside.

Why You Should Visit:
Compared to other mosques in Istanbul, this one is significantly easier to access because of its free admission and central location.
Timings are strict, a dress code is enforced and the queues are long, but the sense of tranquility that you get inside (even with crowds around) is worth it all.

Tip:
Go early to avoid queues and if you need to wait, look at the details rather than focus on the line. The details in Islamic architecture/design are what sets it apart.
Close by, there are places to eat and drink if you need sustenance after or before visiting.
You could also simply walk around it as much as you are allowed, and snap some pics.

The Yerebatan Sarnıcı or the Basilica Cistern translates as “Cistern Sinking Into Ground” and is one of the many ancient cisterns that are present in the city of Istanbul. Located near the Hagia Sophia, on the peninsula of Sarayburnu, it was built in the 6th century AD by the Byzantine emperor Justinian the first. The name is derived from the Stoa Basilica upon which it was built. The Basilica was said to be built by Ilias and housed many structures and gardens. Historical texts state that over seven thousand slaves were involved in the construction of the Cistern.

The cistern used to provide a filtration system for the water for the Great Palace of Constantinople and surrounding buildings on the historic First Hill. After the Ottoman conquest, it continued to provide water to the Topkapi Palace and continues to do so in modern times. It has undergone many restorations, both by Ottoman emperors and the Roman emperors before them.

Today, the cistern is open to visitors and houses many historical relics like the Medusa columns and triumphal arches. The former can be viewed in the cistern's North West corner.

Why You Should Visit:
Great (spooky) atmosphere that makes for magnificent photos and the preservation of history is done remarkably.
Right next to Hagia Sophia, Topkapi Palace, and the Blue Mosque, so easy to fit it in along with the other attractions.

Tip:
Watch your step as some parts (near Medusa heads) can be extra slippery, and take a jacket especially if you get cold easily.

Hagia Sophia is a significant Byzantine structure in Istanbul, renowned globally as one of the most impressive monuments. Initially constructed as a Christian church during the 6th century CE (532–537), it was commissioned by the Byzantine emperor Justinian I. The building's architecture mirrors the region's religious history with minarets, Islamic inscriptions, and intricate Christian mosaics.

The Hagia Sophia, recognized by UNESCO as a World Cultural Heritage site, stands out as a significant architectural achievement. Its grand dome, reaching a height of 180 feet and a width of 100 feet, marked a pivotal moment in architectural design. This building is accented by four minarets from the Ottoman period, added after its initial construction.

The Hagia Sophia has undergone numerous changes in its role through history, initially serving as a cathedral and becoming the core of the Eastern Orthodox Church for almost a thousand years.

When the Ottomans took over Constantinople in 1453, Sultan Mehmed II transformed it into a mosque, leading to the removal of many Christian features and the concealment of Christian images.

What stands out about the Hagia Sophia is its blend of Islamic and Christian symbols, showcasing a unique mix of religious histories. It houses a central mihrab pointing towards Mecca alongside a mosaic of the Virgin Mary and Jesus, reflecting its past as both a cathedral and a mosque.

The building is also home to stunning mosaics, including the notable 13th-century Deësis mosaic featuring Christ, John the Baptist, and the Virgin Mary.

An interesting part of the Hagia Sophia is the 'wishing column' located in the northwest section, believed to grant wishes or healing to those who follow a specific ritual involving their thumb and wrist. It's said that even Justinian found relief from a headache here.

Today, as the Hagia Sophia returns to being a place of worship, its history museum has moved to the nearby Ibrahim Pasha Palace, just a short walk from the mosque.

Why You Should Visit:
Unique in being both a church and a mosque, with pertinent symbols omnipresent.
The multi-domed enclosure is so mesmerizing that it's hard to take one's eyes off it!

For most tourists, the Topkapi Palace is usually number one on the list of places to visit in Istanbul. This grand palace was the official residence of the Ottoman Sultans for almost 400 years and is also a UNESCO world heritage site since 1985.

The Topkapi Palace is built on a huge scale with four courtyards and a Harem, and each location therein houses incredible displays of Islamic art, holy relics and history. The most prized collection is that of the Islamic relics which include Prophet Mohamed’s (PBUH) sword along with the swords of his closest companions, the cloak of his daughter Fatima and other holy relics.

The spacious grounds, the many gardens and rest stops are ideal for strolling at one's leisure, but most of the exhibits have very long waiting lines, especially the Harem and the Islamic Relics displays. There is a museum shop, a cafe and also a coffee shop for tourists. To visit all the exciting places and displays in the Topkapi Palace, you need a full day or, ideally, a tour should be booked.

Why You Should Visit:
Probably the world's finest museum of applied arts; as someone who loves beauty, you will cry from the visual experience of some of the objects displayed.
And, obviously, at the end of your tour, you're welcome to take a walk around the cafe area that overlooks the Bosphorus Strait... Breathtaking!

Tip:
Do come early in the morning to avoid crowds and rent an audio guide (available in several languages) to maximize the experience.
If you want to rent the audio guide, make sure to have a valid ID ready.
Note that you cannot take photos or videos in most of the exhibit halls.

One of the city's most distinctive sights, this great fortification dating back to 1348 was erected by the mercantile Genoese Italians as a vantage point over the city walls and was subsequently used as a fire lookout tower until as recently as the 1960s. At nine stories and 67 meters in height, it is one of the best places to put Istanbul's defining landmarks in a cityscape perspective: all major sights are within easy view and you can walk around the outside platform for a full 360-degree look – provided, of course, the weather is right.

The walk to the tower, which is situated on high ground, can be strenuous for some; don't be afraid of the tower climb, however, as you'll ride in a very modern elevator. While you're there, you can have a drink from the cafe upstairs and prolong your time just a bit more. The lively area around the tower is home to some interesting restaurants, bars and cafés, and you can also take a leisurely walk up Galip Dede Caddesi with its abundant musical instrument shops.

Tip:
Be sure to pick an off-peak time. The tower opens at 9am, so aim to make your way up around then or around sunset. In the evenings, the restaurant hosts a dinner/cabaret show including the always popular belly-dancing.

This is the modern, most organic facet of Istanbul: full of life, restaurants, consulate buildings, bookstores, music stores and art galleries: a nice mix of everything. One could also say that it's the city's most Westernized part and clearly very fashion-forward in a distinctly European way. Traveled by millions of people and vibrant every hour of the day, it comes to life especially at night with street vendors, live music, cafes, bars, pastry shops... you name it – it's probably there.

Perhaps the main feature of Istiklal is the nostalgic red tram – the only vehicle permitted – that links the Taksim and Tünel squares; while it doesn't take you far – just up and down the street – it is a must-try experience to feel the impact of so many pedestrians around you: different people from all over the globe, diversity in all its glory!

Aside from shopping opportunities, look out for historic cinemas (like Atlas, Beyoglu), historical passages (Hazzopulo, Suriye and Çiçek), churches (the ancient Saint Mary Draperis, the impressive Venetian Gothic gatehouse of the Church of Saint Antoine), consulate buildings, and innovative art galleries (check out SALT Beyoğlu, ARTER, and the Mısır Apartments), as well as excellent examples of 19th-century Neo-Classical and Art Nouveau architecture to admire.

Lots of small interesting alleyways lead off the main street, so do not hesitate to take little excursions – you can find a bevy of food (including the Turkish variety of tapas), drink, coffees, trinkets, souvenirs... at generally better prices. Climb up and down the stairs, have a view of the colorful taverns and terraces around, or get dramatic and attend the so many live show music of Turkish singers.

Safety tip:
Keep a hand on your valuables and eyes anywhere but in front of you (a neat trick that clears your path). Avoid walking the minor streets after midnight.

The Ottoman sultans shifted from Topkapi Palace to the newly built Dolmabahce in the 1850s. Designed by the renowned Armenian architect Garabet Balyan, it is the largest and most extravagant of all the palaces on the Bosphorus – especially the Ceremonial Hall with its famous Bohemian crystal chandelier glowing with 750 lamps, gifted by Queen Victoria.

Sultan Abdülmecid and his family clearly wanted a residence comparable to those of his contemporary European monarchs. On this note, it is quite evident that not only were European luxury goods desirable from an aesthetic viewpoint, but also from a symbolic one. The palace not only makes use of European goods but also of European technology to indicate that the Ottoman Empire has not been outdistanced by Europe.

Guided tours are broadly divided into two sections: the public and the private (known as the Selamlik and the Harem, respectively), access to which is given by separate tickets. Interiors are fairly well-preserved and many of the personal belongings of the Sultans and their families on display. Unfortunately, photography is not allowed inside.

Outside, there is a small, but attractive garden around the buildings, with magnificent magnolias, little water-lily ponds, and excellent views over the Bosphorus.

Tip:
Going early is highly encouraged – you'll have entire rooms all to yourself!
The audio guide is a must if you want to get into the cultural benefit of the visit.
Consider taking a rest at the small outdoor cafe in-between visiting the Selamlik and the Harem.
Several good restaurants are nearby on a popular street nearby (Şair Nedim Cd.) that you can walk to in five minutes.
