During the Ottoman period the town was called "Biograd" or "Belgradčik". It is recorded under this name until 1833. A Venetian-Dalmatian source from the first half of the 17th century recorded that "Biogradaz" was a fortress with several towers. In the second half of the 18th century, it was noted that town lies along the Dalmatian border, and that the it is well fortified, but that it has little artillery. The fortress was abandoned in 1851 and partially demolished in 1882.
