Cathedral and Bell Tower

The Cathedral of the Assumption (Stolnica Marijinega Vnebovzetja) occupies the north side of Titov Trg alongside the Praetorian Palace. The exterior is Gothic, with a Romanesque element in the lower facade, but the interior was remodelled in Baroque style in the 18th century. The contrast between the serious Gothic stonework outside and the lighter, painted interior within is typical of many Venetian Adriatic churches.

The adjacent Bell Tower stands separate from the cathedral — a common Italian and Venetian arrangement — and is the most prominent vertical element in the Koper skyline. You can climb the tower by stairs (204 steps) and reach an open platform with 360-degree views over the old town, the port, the Adriatic, and on clear days, the Venetian lagoon in the distance. The staircase is steep but the climb is worth it.

The cathedral holds several notable paintings, including works by the Venetian painter Vittore Carpaccio. The main altarpiece depicts the Dormition of the Virgin and is one of the best paintings in the Slovenian Littoral.

A story
The Bell Tower of Koper is the oldest building on Titov Trg, its base dating to the 12th century when Koper was an independent commune. The tower was built in stages — the medieval base was extended upward in subsequent centuries, and the current top section, with its octagonal drum and open belfry, was added in the 18th century. Climbing it gives you the best aerial view of the old town's medieval island plan.
