Citadels are the historical monuments that usually have a deep footprint of history on their foreheads. Tabas Citadel (Kohan-Dej) is one of the oldest monuments that is located in Tabas, Vaez Tabasi Street, in the Southern Khorasan Province. It dates back to more than 1000 years ago. This citadel is considered as the most important historical attraction of Tabas. The citadel had been renovated several times. When spring arrives, life reappears in the history of Tabas and the presence of people in historical buildings, including Tabas Citadel, is a new soul in the body of this citadel. It seems that the citadel was developed by Mir Hossein Khan in the 8th Century and has 6 towers. One of the most interesting features of Tabas Citadel (Kohan-Dej) is that it has witnessed a lot of happenings and has historically hosted many people such as Nasir Khusraw, a well-known poet of Iran, who was the guest of this castle for 17 days. The cultural heritage has begun efforts to revitalize and restore this monument in the past decades, which has been dismantled from many parts, and the corridors and walls of the citadel have restored.
