Built in 1310 on the site of a former 12th century wooden fortress, Fagaras was surrounded by a deep moat which, in times of war or social unrest, could easily be filled with water from a nearby mountain brook. A bridge over the moat provided the only access point. The fortress boasts three floors and five towers.
