The castle is the center of Skanderbeg’s rebellion against the Ottoman Empire. Inside the castle is the Teqe of Dollme of the Bektashi, the National Skanderbeg Museum, the remains of the Fatih Sultan Mehmed mosque and its minaret, an ethnographic museum and a Turkish bath.
Ottoman troops attacked it thrice, in 1450, 1466 and 1467, but failed to take control. It was this impregnable fortress that helped George Kastrioti Skanderbeg defend Albania from the Ottoman invasion for more than two decades.
The museum was inaugurated on November 1982. Designed by architects Pirro Vaso and Pranvera Hoxha. The museum has the character of a memorial with traditional stone towers and medieval Romanesque architecture.
