Rozafa castle (Albanian: Kalaja e Rozafës) is a castle near the city of Shkodër, in northwestern Albania. It rises imposingly on a rocky hill, 130 metres above sea level, surrounded by the Buna and Drin rivers.
Due to its strategic location, the hill has been settled since antiquity. It was an Illyrian stronghold until it was captured by the Romans in 167 BC. The 19th-century German author and explorer Johann Georg von Hahn suggested that the ancient and medieval city of Shkodër was located immediately south of the Rozafa hill, between the hill and the confluence of Buna and Drin. The fortifications, as they have been preserved to date, are mostly of Venetian origin. The castle has been the site of several famous sieges, including the siege of Shkodra by the Ottomans in 1478 and the siege of Shkodra by the Montenegrins in 1912. The castle and its surroundings form an Archaeological Park of Albania.
