High above the Rižana Valley, on the edge of the Karst Mountains, stands the Črni Kal Fortress. From here, you have a beautiful panoramic view of the Bay of Koper and the surrounding villages.
From Strmec Castle (Socerb), you have a magnificent view of the Gulf of Koper and Trieste. Below the castle is a karst cave connected to the castle courtyard.
Like the cherry on top of the cake, Socerb Castle, named after Trieste's patron saint and martyr, St. Servulus, reigns over the village of Socerb. Its surroundings offer a magnificent view of the Gulf of Trieste.
