Monte Ermada, also known as Hermada is a hill on the Karst Plateau, near the border between the Italian provinces of Trieste and Gorizia. Most of it is located in the municipality of Duino-Aurisina, with its eastern appendages in Slovenian territory. It consists of a massif with several peaks: besides the main peak, which stands 323 meters above sea level, there are Jastreb, Goljak, Grižnik, Vrh Griže, Cocco/Na Kokem, Frščak, Ter, Gabrnjak, Dosso Petrinia/Veliki Škrnjak, Dosso Petrinia inferior/Mali Škrnjak, Lisičji Vrh and the isolated Castelliere di Ceroglie/Ostri Vrh. Small valleys, carsic swamps and sinkholes are located between the peaks. The small village of Cerovlje, a hamlet of Duino-Aurisina, is located at the foot of the Ermada.
