The main entrance to Kotor’s fortified city, known as the Sea Gate, was built in 1555 during Venetian rule, from 1420 to 1797. Above the gate, you’ll notice the winged lion of Saint Mark, the emblem of Venice, also visible at several other points around the old town. Sharing the same space is a later historical layer: a red communist star and a post–Second World War inscription reading, “What belongs to others we don’t want, what is ours we will never surrender”, a slogan commonly attributed to Josip Broz Tito, a communist revolutionary and former president of Yugoslavia.

Although sections have deteriorated over time, the remaining structure still conveys the scale and ambition of Kotor’s fortifications. Originally accessible only from the sea, the gate has subsided by more than 70 centimeters since its construction, largely due to the immense weight of its stone masonry and the unstable ground beneath.

As you pass through the gate, look for the 15th-century stone relief of the Madonna and Child, flanked by Saint Tryphon, Kotor’s patron saint, and Saint Bernard of Clairvaux. Beyond it, the space opens directly onto Arms Square, once the city’s main administrative and military hub and today the natural starting point for exploring the cobbled streets of Kotor’s old town.

As you pass through the Sea Gate, you’ll find yourself in Arms Square, the largest and most open space within Kotor’s walled city. This square has long served as the city’s civic and military center and today remains busy with cafes, shops, banks, and public buildings arranged around its edges.

Facing back toward the Sea Gate, look slightly to your left to locate the Clock Tower, built in 1602. Its noticeable tilt is the result of earthquake damage rather than age alone, and its form blends Baroque features with older construction traditions. Nearby, close to the base of the tower, stands the medieval pillar of justice, once used for public punishments and official proclamations.

Now go toward the western side of the square. Here you’ll see the Prince’s Palace, historically the seat of Venetian administration and now incorporated into Hotel Cattaro. Adjacent to it is the former Arsenal, where weapons were produced and stored during Venetian rule. This area was the operational heart of Kotor’s defenses, and soldiers once gathered here to collect arms and prepare for battle.

As you look toward the western side of the square, on your right you’ll come to the building that houses the Napoleon Theatre. . Originally constructed in 1762 as a military warehouse for supplies and food, it was converted into a theater during the French administration in the early 19th century, becoming one of the earliest theaters in the Balkans.

From this square, the events of 1539 still resonate. It was here that defenders organized their resistance when Kotor withstood a siege by the Ottoman admiral Hajrudin Barbarossa, holding out for more than a week until his fleet withdrew.

The Church of Saint Nicholas was consecrated in 1909, replacing an earlier 17th-century Orthodox church that was destroyed in a fire on Christmas Eve in 1896. Its commanding appearance is defined by two tall bell towers, topped with black domes and gilded crosses, which were donated by Imperial Russia, reflecting close Orthodox ties at the time.

The church was designed by Ćiril Iveković, a well-known Croatian architectural engineer and conservationist active across the Adriatic region, from Zadar to Kotor. His work included churches, rectories, and public buildings, and he also played an important role in heritage preservation.

Architecturally, the church follows a Neo-Byzantine style, its interior being dominated by a richly carved iconostasis completed in 1908, along with an extensive collection of icons. Among them is a revered copy of the Icon of the Holy Mother of God Three-handed. The church also preserves religious books, liturgical objects, and artworks donated by prominent families from Kotor and the surrounding region.

Today, Saint Nicholas is the main Orthodox church in Kotor and the only one in the Old Town where daily liturgies are held. The flag of the Serbian Orthodox Church is typically displayed on the facade, marking its active role in the city’s religious life.

The Church of Saint Mary, originally built in 1221 atop the site of a 6th-century basilica, holds significant historical and religious importance in Kotor. Notable features include its remarkable 20th-century bronze doors adorned with bas-reliefs, remnants of 16th-century frescoes attributed to Greek artists, and a striking larger-than-life crucifix. However, one of its most significant aspects is the presence of a glass coffin containing the body of Blessed Osanna of Cattaro (1493–1565).

Osanna's story is one of profound devotion and selflessness. Opting for a life of prayer, she chose to become an anchoress, secluded within a small cell attached to the church. Despite her solitude, she remained deeply connected to her faith, attending Mass through a window and offering prayers for those who sought her intercession. Following the destruction of her initial hermitage by an earthquake, Ossana relocated to a cell at Saint Paul's church and faithfully adhered to the Dominican rule for the last 52 years of her life.

Even in death, Osanna continued to be revered by the people of Kotor, who regarded her as a saint and protector of their city. Her incorrupt body was initially housed in the Church of Saint Paul until 1807 when it was transferred to the Church of Saint Mary, where it remains to this day. In 1905, the process for her beatification commenced in Kotor and was successfully completed in Rome.

Rising above Kotor on the slope of the mountain, this fortress stands about 260 meters above sea level and is reached by a steep path that climbs through a long series of bends and more than 1,300 stone steps. From the top, the view opens across the Old Town’s rooftops, the winding bay below, and the surrounding mountains.

The fortress takes its name from the Church of Saint John the Baptist, located within the upper citadel and first mentioned in 1440. The church served the garrison responsible for guarding the city’s walls and gave the entire complex its traditional name. The defensive system surrounding Kotor is extensive: the walls stretch for several kilometers, climbing from the shoreline up the mountainside, with sections that vary greatly in height and thickness depending on terrain and period of construction.

The fortifications developed gradually over many centuries. Early defensive structures are traditionally linked to the reign of Emperor Justinian in the 6th century, though much of what is visible today reflects later rebuilding. The walls and bastions were repeatedly strengthened, with their present form largely shaped during the Venetian period, particularly in the 16th and 17th centuries, in response to Ottoman threats.

Partway up the ascent stands the Church of Our Lady of Health, built in the 16th century following outbreaks of plague. It became a place of prayer for protection and healing. Along the route, several small chapels once marked the path; their painted panels depicting Marian feasts are now preserved inside the church.

Boka Navy Square is a small but historically dense square in Kotor’s Old Town. The square opens slightly wider than the surrounding streets and functions as a junction between residential, civic, and maritime spaces.

If you face north, the most prominent building in front of you is the Grgurina Palace, a Baroque residence built in the early 18th century with stone brought from Korčula. Today it houses the Maritime Museum of Montenegro, but from the outside, notice the balanced facade and stone balconies that reflect the wealth of Kotor’s seafaring elite.

In the middle of the square, look down for a square stone cover set into the pavement that marks the Karampana well, a small stone structure that supplied drinking water to the city for centuries. Its current form dates to the early 18th century. Look closely at the wrought-iron structure above it, traditionally attributed to local blacksmiths. Although it stopped functioning in 1958, the well remained a long-standing gathering point for news and conversation.

Now turn toward west. Along this side of the square, you’ll see a row of souvenir and handmade-goods shops, their display windows and awnings spilling toward the stone pavement and giving this edge of the square a more commercial, everyday feel.

Saint Tryphon Cathedral is one of the city’s most important historical monuments, consecrated in 1166 and built on the site of an earlier 9th-century church dedicated to Saint Tryphon, Kotor’s patron saint.

The cathedral is a three-nave Romanesque structure that has undergone multiple phases of restoration. The most significant changes followed the 1667 earthquake, which damaged much of the facade and caused the collapse of the original bell towers. The towers were rebuilt in a Baroque style, giving the cathedral its present silhouette, while the facade retains Romanesque elements alongside later decorative additions. The rose windows, altered over time, reflect a blend of stylistic influences rather than a single medieval form.

Inside, the cathedral preserves an important collection of religious art and liturgical objects made of gold and silver, many produced by local craftsmen. Traces of medieval fresco decoration, attributed to Greek-trained painters, survive, though much has been lost. One of the interior’s focal points is the 14th-century ciborium above the main altar, combining Romanesque and Gothic features. Behind it stands the Golden Altarpiece, depicting Christ, the Virgin Mary, Saint John the Baptist, Saint Tryphon, and sixteen additional saints, a key work of Kotor’s goldsmith tradition.

Access to the cathedral includes entry to the Sacral Art Collection, which displays reliquaries, icons, manuscripts, and vestments associated with the cathedral’s history. The modest entrance fee supports conservation while allowing the cathedral to function primarily as a place of worship.

Adjacent to the cathedral is the Bishop’s Palace, historically the residence of Kotor’s bishops. The building incorporates elements of earlier noble residences, including associations with the Drago family, reflecting the close ties between ecclesiastical authority and local aristocracy.

Often regarded as one of the oldest thoroughfares in Kotor, Craftsmen Street follows the city’s main north–south axis, running between the South Gate and the North Gate at the foot of the mountain. While its exact layout evolved over time, the street broadly follows the line of the ancient town’s primary route, linking Kotor’s key entrances from early periods onward.

From the Middle Ages well into the early modern era, Kotor was known for its skilled artisans, and this street became the city’s main craft corridor. Workshops were traditionally grouped by trade, creating a dense concentration of economic activity. Historical records, including documents from 1326, list dozens of professions active in the town, among them shoemakers, tanners, butchers, stonemasons, goldsmiths, blacksmiths, swordsmiths, and bakers.

As you walk today, souvenir shops and small studios occupy many former workshops, but traces of the street’s earlier function remain visible. Along the route, you’ll encounter religious buildings that once served both artisans and residents. The Church of Saint Anne, dating to the 12th century, was rebuilt following damage in the 1979 earthquake. Nearby stands the Church of Saint Paul, constructed in 1263.

Taken together, Craftsmen Street offers a compressed view of Kotor’s urban life, where trade, worship, and everyday movement once unfolded along a single, enduring spine of the city.

The Beskuća Palace stands on the street leading from the Arms Square to the Flour Square, opposite the Bizanti Palace, and was constructed in 1776, replacing older structures that occupied the site. It is believed that one of these structures was the residence of the prominent Bizanti family, from which the palace inherited its portal.

Featuring a simple architectural design with clean lines and minimal decorative elements, the palace is distinguished primarily by its aforementioned Gothic portal, widely regarded as a masterpiece of floral Gothic architecture along the entire eastern Adriatic coast. At its center is the family's coat of arms, depicting a winged lion, while below it, a Latin inscription reads: "Si deus com nobis, quis contra nos" ("If God is with us, who can be against us").

Originally belonging to the Beskuća family from Prčanj, the palace signifies the family's ascent to prominence in the late 18th century, fueled by their success in maritime trade. Bestowed with nobility, the family amassed considerable wealth and possessed numerous estates and residences across the Bay of Kotor, as well as in Venice and Constantinople.
