The Monumento al Infante D. Henrique is a bronze statue of Prince Henry the Navigator, a 15th century Portuguese explorer and navigator who played a significant role in the Age of Discovery. The statue was created by Portuguese sculptor Leopoldo de Almeida, and was donated to the city of San Juan by the government of Portugal in 1958.

The monument serves as a tribute to the enduring friendship between Portugal and Puerto Rico, and is an important symbol of the shared history and cultural ties between the two nations. In addition to its historical and cultural significance, the Monumento al Infante D. Henrique is also a beloved landmark among locals and tourists alike, who come to admire its beauty and learn more about its history and significance.

Proudly presiding over the bay of San Juan is the imposing La Fortaleza (Fortress), formally known as the Palace of Santa Catalina, the official residence of the Governor of Puerto Rico. The narrow road leading to the building, called Fortaleza Street, is the main artery of San Juan's historic quarter, cutting through most of it, and is also the oldest street in the area. It starts from Columbus Square and for the whole of its duration is lined with governmental buildings, hotels, perfumeries, craft shops, jewelry stores, and restaurants, gradually transforming into Avenue Juan Ponce de León in the east.

Just like many other colorful cobblestone streets in Old San Juan, each one more photogenic than the other, this thoroughfare is an important tourist attraction, in large part due to its historical and cultural significance. Visiting Fortaleza Street should be an integral part of every Old San Juan itinerary.

While the walled-in Old City has no shortage of vibrant photo spots, Fortaleza Street stands out above the rest due to the display of umbrellas – at the end of the street, near La Fortaleza itself – creating an overhead canopy that makes it particularly recognizable. These umbrellas tend to change colors during the year, from rainbow to all pink. Before the umbrellas, La Fortaleza Street was adorned with colorful kites.

Standing guard at the eastern gate, north of Columbus Square, is an imposing 18th-century fortress, called San Cristóbal. Contrary to her sister, El Morro, which was designed to protect from attacks by sea, the San Cristóbal Fort guarded the city against the enemy approaching by land, for which purpose it created a crossfire with El Morro over the bay. The citadel construction began in 1634 and was meant to strengthen the Spanish position in the face of imminent English and Dutch invasion.

The fort was named San Cristóbal in celebration of the Spanish victories which enabled ejecting of the English and Dutch interlopers from the island of the same name in the Lesser Antilles, which was then part of the insular territorial glacis of Puerto Rico.

When finished in 1783, the Fort San Cristóbal covered nearly 27 acres of land and practically wrapped around the whole of San Juan, with the entry to the city sealed by the San Cristóbal's double gates. After almost 100 years of relative peace, about a third of the fortification was demolished, in 1897, to help ease the flow of traffic in and out of the walled city.

The Fort San Cristóbal is now a listed National Historic Site. It is particularly worth visiting as the largest fortification ever built by the Spanish in the New World, where the first shots of the Spanish-American War were fired. If you're a keen photographer, San Cristobal is a goldmine of panoramic views of the coast, from Old San Juan to Condado and beyond.

Tip:
Guided tours by local rangers visit the extensive tunnel system connecting various sections of the fort. There is an exhibition of military clothing. Be sure to visit the overlook for the Devil's Sentry Box ("Garita del Diablo"), from which, according to legends, soldiers mysteriously disappeared. Tickets to San Cristobal or El Morro can be used to enter either of the forts.

Santa María Magdalena de Pazzis Cemetery is a colonial-era cemetery located in Old San Juan, Puerto Rico. It is the final resting place of many of Puerto Rico's most prominent natives and residents. Construction began in 1863 under the auspices of Ignacio Mascaro. The cemetery is located outside the walls of Fort San Felipe del Morro fortress, one of the island's most famous landmarks.

It was named in honor of Saint Maria Magdalena de Pazzi. The location of the cemetery is central to the Puerto Rican belief in the separation of death and life. The colonial Spanish government at the time the construction of the cemetery commenced, viewed death with fear because it was a mystery. Therefore, they decided to build the cemetery to overlook the Atlantic Ocean to symbolize the spirit's journey to cross over to the afterlife.

The Fort San Felipe del Morro, or simply El Morro, is a 16th-century citadel on the northwestern tip of the San Juan islet, named in honor of King Philip II of Spain. It was the second military installation, after La Fortaleza, built in what is now known as the Old Town.

The construction began in 1539, authorized by King Charles V, and was finished in 1790. During that period, El Morro had been transformed from a promontory mounted with a cannon to a six-level fortress designed to guard the entrance to the bay of San Juan from seaborne invaders. Many more structures were added to the complex over the next 400 years; the outer walls, built initially 6 feet (1.8 m) thick, were augmented to 18 feet (5.5 m) by the end of the 18th century.

Thanks to El Morro, the Spanish were able to defend Puerto Rico from invasions by the British and the Dutch, as well as pirates. In 1898, following the Spanish-American War, the island changed hands from Spain to the United States. El Morro was actively used as a military installation during the First and Second World Wars.

In 1961, the US Army retired El Morro, passing it on to the National Park Service to use it as a museum. In 1983, El Morro and the walled city of Old San Juan were declared UNESCO World Heritage Sites.

Tips:
A ticket to El Morro allows entry to the Castillo San Cristóbal (and vice versa) for a single fee.

Plaza La Rogativa is the most scenic square in San Juan, offering a 180-degree views of the San Juan Bay. From here, you can also get a clear view of the San Juan Gate and La Fortaleza, much as of the El Yunque national forest in a distance.

The name "Rogativa" means "Procession". According to a legend, during the 1797 attack by the British army, the governor of San Juan ordered a "rogativa" by a group of women, led by the bishop, to march through the city streets at night. Started from the San Juan Cathedral, the procession carried torches and crosses, while singing hymns along the way. The British mistook these sights and sounds for the arrival of Spanish Army reinforcement and gave up the attack. Commemorating that event are the four bronze statues in the center of the square.

Due to its historic significance and scenic beauty, Plaza La Rogativa is also popular a spot for wedding ceremonies. If nothing else, come here in late afternoon to watch the sunset over the San Juan Bay.

Built in the late 1700s, the San Juan Gate is a giant (40 feet high) structure, the last remaining of the original five gates carved into the three-mile wall that once surrounded the city. Today, the wall wraps around Old San Juan, from the cruise ship piers on San Juan Harbor to the capitol on the Atlantic.

Originally, each gate had a designated function. The red gate of San Juan played a symbolic role, serving as the main entrance to the city, and was named in honor of Saint John the Baptist. The first thing you notice approaching it is the inscription of The Sanctus ("Holy") hymn from the Catholic liturgy.

The city wall is the most enduring symbol of Puerto Rico and was built by the Spanish between 1539 and 1782. Made of sandstone, rubble, and mortar blocks – 20 feet thick, the wall measures 45 feet wide and 40 feet high in some parts and was meant to protect San Juan from invaders, notably the English, the Dutch, and the Americans. Its iconic sentry boxes now symbolize the island's Spanish heritage and resilience in an ever-changing world.

Nearly impenetrable to foreign attack, the city wall proved defenseless, nonetheless, against modern automobile traffic, pollution, and misguided attempts to preserve it that have seriously endangered the wall, leaving it crumbling in some places.

Currently a National Historic Site, the city wall is maintained by the National Park Service which attempts to recreate the magic mixture of sand, water, and limestone that was once used to stucco the wall. Along with the adjoining fortresses of El Morro and San Cristóbal, the city wall attracts 1.2 million visitors each year.

Tip:
As you walk through the gate, just pause for a second and notice how thick the walls really are. Also, check out the street vendors outside, on the corner, offering refreshments including Puerto Ricans' favorite, piragua.

Arms Square is the de-facto central square of San Juan. Over the years, it has changed several names relative to the functions it served. Initially, in 1521, it was called Vegetables Square. Then, during the 17th-19th centuries, it was known as Arms Square, for being the grounds for military drills. After that, in the early 20th century, it turned back to being called Vegetables Square once again, serving as a marketplace, before it finally re-assumed the Arms Square title.

The plaza is modeled on the classic squares of Madrid and Mexico City. Although it factually existed for centuries, it was not until 1840 that the city council approved its proper development, which started in 1851. It was at that time that the four bronze statues, oil-coated to simulate marble, representing Commerce, Industry, Science, and the Arts, arrived here (there were a total of eight statues to be installed, but the other four were lost). In 1872, the original statues were replaced with the new marble ones, representing the Four Seasons, put in the four corners of the square.

In 1955, two circular fountains and two lampposts in the center were added. The four statues were then configured in a circular fountain outside the Palacio de la Real Intendencia, which is the seat of the Department of State of Puerto Rico, on the western side of the square.

A highlight of the northern side is the Casa Alcaldía – home of the San Juan City Hall. Built in 1789, this Spanish colonial-style edifice with twin turrets resembles its sister building in Madrid. The tinkling of the fountain, the comfortable seating in the shade of the trees, and the presence of several old-style coffee booths selling snacks have long attracted tourists as a good spot for a sightseeing break when you can stretch out your feet and soak up some of the everyday comings and goings.

The laid-back atmosphere of the place also made it a popular gathering venue with locals, offering a chance to buy kids some traditional treats (like sesame-seed lollipops or coconut candies), watch shows, play dominoes, or chit-chat with friends.
