The Krujë castle (Albanian: Kalaja e Krujës) is a castle in the city of Krujë, Albania and the center of Skanderbeg's battle against the Ottoman Turks. The castle withstood three massive sieges from the Turks, with garrisons usually no larger than 2,000-3,000 men. Mehmed II "The Conqueror" himself could not break the castle's small defenses. Today it is a center of tourism in Albania, and a source of inspiration to Albanians. Krujë Castle is situated at an altitude of 557m.
