The Citadela occupies the highest point of Budva's old town peninsula and is the most prominent landmark on the waterfront when approaching by sea. The current fortifications date from the Venetian period, though the site has been fortified since antiquity. It was badly damaged in the 1979 earthquake but has been restored, and a small museum inside holds maritime artefacts, antique weapons, and a modest library of old books in several languages.
The main reason to climb up here is the view. From the battlements you can see the full arc of Budva Bay, the hotel-lined Slovenska obala beach below, the old town streets directly beneath you, and the open Adriatic to the west. There is also a small open-air theatre built into the citadel walls used during the summer festival. Entry costs a few euros; it is one of the better ways to spend an hour in Budva.
