An Austro-Hungarian fortress from 1853 on the rocky island of Lastavica
Mamula Fortress stands on the small rocky island of Lastavica, right at the entrance to the Bay of Kotor, between the Prevlaka and Luštica peninsulas. It was built by Austro-Hungarian General Lazar Mamula in 1853 as part of a defensive system guarding the bay's entrance, together with the fortresses of Arza and Prevlaka. The fortress occupies nearly 90% of the island's surface, which has a diameter of 200 metres, and is considered a masterpiece of military construction. During World War II, the fortress was converted into a concentration camp where more than 2,000 people were imprisoned. Since 2023, the building has operated as the luxury boutique hotel Mamula Island by Banyan Tree, alongside a memorial gallery that preserves the history of the site.

Highlights

Mamula Fortress was built between 1850 and 1854 and is considered one of the finest examples of Austro-Hungarian military architecture on the Adriatic. The circular form of the fortress perfectly follows the outline of the island, which has a diameter of 200 metres, while its walls of large, precisely hewn stone blocks give it a monumental appearance rising directly from the sea. It was part of a three-fortification system — together with Arza and Prevlaka — that protected the entrance to the Bay of Kotor. According to many experts, the fortress remains a masterpiece of military construction to this day.

From 30 May 1942, Italian fascist forces converted the fortress into a concentration camp where more than 2,000 people were imprisoned, mainly women, children, and men from the Bay of Kotor region. Many of them did not survive their imprisonment. A commemorative plaque at the fortress entrance pays tribute to the victims, and within the hotel a memorial gallery marks the 170-year history of the fortification. The Yugoslav film 'Campo Mamula' from 1959, directed by Velimir Stojanović, depicts the events of that period.

Since 2023, Mamula Fortress has operated as a luxury boutique hotel managed by the Banyan Tree group — the first such hotel of the group in Europe. The hotel features 32 rooms and suites housed in restored casemates and towers of the fortress, three pools, a private beach, a 748 square metre spa centre, three restaurants and four bars. Condé Nast Traveler included it on its list of 'Best New Hotels in the World 2024'. The rooms offer panoramic views of the Adriatic Sea from both sides — towards the open sea and towards the interior of the bay.

Just a few minutes by boat from Mamula Fortress, along the coast of the Luštica peninsula, lies the Blue Cave — a sea cave renowned for the brilliantly blue colour of its water, created by the refraction of light through underwater entrances. The interior of the cave is characterised by enormous rocks bathed in shades of blue, creating a visual experience that is hard to forget. Visitors can swim through the interior of the cave and photograph it from different angles. The Blue Cave is regularly combined with a visit to Mamula Fortress as part of boat tours departing from Herceg Novi.
