The Chaqchan Mosque (Urdu: مسجد چقچن; meaning “The Miraculous Mosque”[1]) is a mosque in the city of Khaplu, in the Gilgit-Baltistan region of northern Pakistan. Dating from 1370, the mosque is one of the oldest in the region, and dates from the time when the area’s populace converted en masse from Buddhism to Islam.[2][3] The mosque shares similar architecture as those built in the Kashmir Valley.[4] It is a perfect blend of Tibetan, Mughal and Persian style of architecture.[5]
