    Fortress in Herceg Novi's old town

    Forte Mare, the fortress guarding Herceg Novi's harbour

    Forte Mare, the «sea fortress», guards Herceg Novi's approach from the water, perched on the rock above the seafront. It was built between the 14th and 17th centuries, remodelled by the Venetians and Austro-Hungarians, and turned into a summer stage in 1952. Since then it has been one of the oldest open-air cinemas on the coast, with views over the mouth of the Bay of Kotor.

    • Herceg Novi's sea fortress, built between the 14th and 17th centuries.
    • Remodelled by Venetians and Austro-Hungarians, with the old Sea Gate.
    • Summer stage and open-air cinema since 1952.
    • Views over the mouth of the Bay of Kotor, the harbour and Igalo.

    Forte Mare is the fortress I'd leave for the end of the day, walking down from the old town to sit up top with the mouth of the bay in front of me. If there's a film or a music night on, I wouldn't think twice.

    Before you go

    What I would keep in mind

    1. 01 Most beautiful

      The best view of the bay's mouth

      The tourist board points out that from the top you see the entrance to the Bay of Kotor, the town harbour, Igalo and the old town.

    2. 02 Worth the splurge

      A cinema that's run for decades

      The fortress has been a summer stage since 1952, and the tourist board counts it among the oldest and loveliest open-air cinemas around.

      Aleksa Šantić's verses

      By the spring at the foot of the fortress, a marble plaque carries lines by the poet Aleksa Šantić dedicated to the Bay of Kotor.

    What I would book

    If Kanli kula watches over Herceg Novi from above, Forte Mare does it from the water. The name says it all, «sea fortress», and it sits on the rock overlooking the promenade and the harbour. For centuries it controlled the way into town by sea, and it’s my favourite spot in the old town to watch the light fade over the mouth of the bay.

    Six centuries on one rock

    The Herceg Novi tourist board describes the fortress as the core of the medieval town founded by Tvrtko I in 1382, built in stages between the 14th and 17th centuries. All that remains of the earliest phase is a section of wall on the south-east side and a narrow staircase on the east. The biggest rebuild was Ottoman, giving it its present dimensions and the nickname «the strong fortress». In the 17th century the Venetians restored it and gave it the name it still bears, and later the Austro-Hungarians, who are responsible for how it looks today, upgraded the upper section and used it as a military communications centre.

    The spring and the Sea Gate

    At the foot of the fortress is a spring with a story. In 1687 the forces of the Holy League, Venetians, Spaniards and papal troops, drained it and left the town without drinking water, which made the conquest easier. Above the spring, a marble plaque carries lines by the poet Aleksa Šantić dedicated to the Bay of Kotor. Higher up is the Sea Gate, with elements of the fortifications from the Bosnian period, which the tourist board rates among the finest defensive architecture in town. Within the walls a passage climbs from the shore to the top. The tourist board rounds off its entry with lines by the writer Miloš Crnjanski, who saw an unusually blue sea beneath Forte Mare, purple sea urchins on the bottom, and imagined Admiral Barbarossa’s sieges from its walls. Read them up there, with the water below, and they make more sense.

    Cinema beneath the battlements

    In 1952 the fortress was turned into a summer stage, and it has been screening open-air films for over six decades. In June, which I describe in Montenegro weather in June, it also hosts Choose Vision, a festival of one and two-night electronic music events. If your dates line up with a show, it’s a wonderful way to see the fortress after dark. The tourist board’s website doesn’t publish daytime hours or an admission price, so I won’t guess them. The Herceg Fest cultural centre runs the summer programme in the fortresses, so check what’s on there.

    How to combine it

    I’d walk down to Forte Mare after climbing Kanli kula, late in the afternoon, then carry on along the promenade towards Igalo for dinner by the sea. For somewhere to sleep nearby, hotels in Herceg Novi splits the options into the old town, the promenade and the Kumbor coast.

    So you do not lose the morning at the ticket office, browse tickets and tours in Forte Mare on GetYourGuide.
