Furg Citadel, (Arg e Furg, also known as Forg citadel and Mirza Rafi Khan citadel), is an 18th-century citadel located in Furg Village in Darmian County, South Khorasan, Iran. Furg Citadel was constructed by Meerza Muhammad Rafiee Darmiany I (Lama). It was registered in the List of National Works on March 18, 2001. Name There are different origin stories for the name of Forg/Furg. One of the more common is that Forg was commonly pronounced Fork among the people. The Dehkhoda Dictionary, in a quote from the Encyclopedia, explicitly mentions that Fork was the name of the ancestor of a family in Iran, and is an Iranian name. Another version is that Fork was the name of the daughter of "Ryan Konouj", an Indian king. Fork was the wife of Bahram Gour (as stated in Borhan), and/or perhaps it stems from the Persian word pour, meaning "son".

It is on the edge of the heights of Darmian Valley, leading to the Asadiyeh plain. The citadel has a commanding view of the village, farms and roads in the area. Furg Citadel covers about 9,200 square meters, extending from east to west. The main entrance of the citadel is in the eastern walls, the lowest point of the citadel. One of the key features of the citadel is its physical and spatial structure, which follows the topography of its location. The main weakness of this location is the close proximity of the citadel to the mountains. This benefit to attackers using cannon was pointed out in Einolvaghaye. Of course, in respect of the problem mentioned above, it ought to be noted that the location of the citadel should be studied within its own time. Perhaps in the era of Naseri (Naser al-Din Shah) in which cannons were vastly used in local wars in the region, this vulnerability of the citadel has been revealed, while; in the early periods that these weapons were not common, perhaps it provided the
