The Karim Khan Castle (Persian: ارگ کریم خان‎‎ Arg-e Karim Khan) is a citadel located in the downtown Shiraz, southern Iran. It was built as part of a complex during the Zand dynasty and is named after Karim Khan, and served as his living quarters. In shape it resembles a medieval fortress.

At times, the citadel was used as a prison. Today, it is a museum operated by Iran’s Cultural Heritage Organization.

Arg-e-Karim Khan was built in 1180 AH (1766-7). Karim Khan invited the best architects and artists of the time and bought the best materials from other cities and abroad for the construction of the citadel of Karim Khan, which was quickly constructed. During the Zand dynasty it was used by the king as living quarters. During the Qajar period it was used as the governor’s seat.

Prince Abdolhosein Mirza Farmanfarma, governor of Fars Province, ordered the miniatures in the citadel to be renovated.

After the fall of the Qajar Dynasty it was converted into a prison and the paintings were plastered over. In 1971 it was given to Iran’s Cultural Heritage Organization. The renovation of the citadel started in 1977.
