Within the boundaries of the significant landscape is the Old Town of Perušić, whose locality called Vrhovina in the Buška parish was mentioned as far back as 1071, where the Frankopans dined. The old town was renamed in 1487 and presented to the new owners - the Perušić brothers, signatories of the Požun Peace in 1491.
During the Ottoman occupation (until 1696), Perušić became an important Turkish stronghold due to its favorable location and proximity to the borders of the Republic of Venice and the Habsburg Monarchy. After Pope Marko Mesić freed Lika and Krbava from the Ottomans, the Turkish population was converted to Christianity and Perušić became part of the Military Territory until the 19th century, when it became part of Banska Croatia.
The old town of Perušić, known as Gradina or the Turkish Tower, is the most famous symbol of the Municipality of Perušić.
The tower is currently in the process of restoration, and according to a recently found blueprint, there were three more watchtowers and stone ramparts around the entire city - today there are only remnants.
