Fethiye Mosque, 15th-century Ottoman mosque in Krujë, Albania

Fethiye Mosque stands in ruins inside Krujë Castle, near the entrance of the Skanderbeg Museum. Only the lower parts of its walls and the base of its minaret remain; there is no dome. It was completed around 1481 and is a Cultural Monument of Albania.

The building was constructed before 1481 under orders from Sultan Mehmed II. It suffered severe damage in 1831 and was later rebuilt during the reign of Sultan Mahmud II.

The name Fethiye comes from the Arabic feth, meaning conquest, and the mosque was dedicated to Sultan Mehmed II, who took Krujë in 1478. It served as a house of worship for Krujë's Muslims until 1937, after which it stood unused. Only the lower walls and the minaret base remain, so no prayer hall or furnishings survive.

The ruin stands inside Krujë Castle, next to the entrance of the Skanderbeg Museum, so it is reached on foot through the castle grounds. Only the lower walls and the minaret base survive; there is no dome or roof, and the site is open to the weather. Allow a short stop while walking between the museum and the castle walls.

The minaret that collapsed in a 1917 storm was famed for its beauty; only its lower part and the lower walls of the mosque remain today. The ruin stands a few steps from the entrance of the Skanderbeg Museum inside Krujë Castle.
