Fortress Tabija (Tvrđava Tabija)
Why visit: A 19th-century Austro-Hungarian fortress, built during the time when this area was a strategic point on the empire’s southern border.
It was designed to monitor the coastline and defend against Ottoman forces.
Though partially in ruins today, the structure is still impressive — with stone walls, tunnels, and even remnants of the old cistern system.
Insider tip: Combine it with a visit to Fortress Haj-Nehaj, which is visible from Tabija and just a short drive/hike away. They make a perfect double for a half-day history + nature tour.
