Those who are interested to history and geology have surely heard of Hamdollah Mostowfi. He was a writer and historian at the Ilkhanate era, whose precious works have preserved his fame among the fans of various sciences.
His tomb is located in a cellar, where a square shaped building was constructed upon it and was turned more into an octagonal shape than into a dome, and all around this building is decorated with Muqarnas. The azure cone shaped dome and the cerulean inscription which is written in Thuluth handwriting introduces Mostowfi’s ancestors and his works. This monument has been distinguished from other historical relics of the town because of the beautiful decorations of Mongol era at every point of this building. This is building is also known by the name of “the long dome” .
This relic was registered in February 9th, 1940 as one of the national relics of Iran.
