Shīrvān
Shirvan lies in the Atrak valley of northern Khorasan, between Bojnurd and Quchan. Near the settlement of Ziyarat stands an old octagonal tomb, built of brick and pierced by arched entrances. A grave inscription records the year 785 of the Islamic calendar, corresponding to 1383–84, though the building's dating and the identity of its occupant have been debated. The monument is a reminder of the long history of the valley and its communities.
