Citadel Baharestan Birjand is one of the historic mansions of Birjand, which is, of course, not a pleasant day. The construction of the Baharestan organ dates back to the time of Amir Alam Khan, the son of Amir Alam Khan. One of the important historical events can be the refugee of Lotf Ali Khan Zand and his companions to the organ.
The main building of the Baharestan of Birjand is an octagon, the first floor consists of separate rooms and chambers, specially for soldiers and government agents, and the second floor consists of a circular central corridor with corridors from which it is branched out. On this floor there are special places for burning torches, as well as cobblestones, overlooking all parts of the citadel.
