Arg of Karim Khan is located in the downtown of Shiraz. This fortress was constructed in Zandiyeh Dynasty upon the order of Karim Khan, the ruler. He hired many professional architects and provided the best materials to build it. The fortress was used as the governors’ place in Zandiyeh and the residential place of local governments in Qajar. The construction of Arg of Karim Khan is a combination of both military and residential architectures. The inner part with beautiful iwans and painted rooms, fountains and gardens masterfully beautify the fortress. All rooms are connected to each other and one can get to every part without stepping outside. The watch towers on four sides of the castle with fosse around it demonstrate the military usage of Karim Khan Citadel. Arg bathhouse is one of the first private bath and was used by the royal family. It was decorated with delightful tiles and makes a nice view. All and all, the whole complex seems like an exciting trip to the past.
