Perched dramatically atop a rocky outcrop just above the sea at the southernmost point of the old town, Forte Mare (in one incarnation or another) has been an integral part of Herceg Novi throughout its history. In fact, it's said that the fortress' first stone was placed by none of that than King Stjepan Tvrtko I when he officially founded the settle in 1382. It's widely used Italian name comes from the time of Venetian rule during the 17th century. Nowadays, in addition to being one of the symbols of the city and a must-visit attraction for tourists, Forte Mare is also one of the venues for the annual Festival of Cinema in August, which explains the projection screen that sits atop it.
