Mosque in Khaplu, Gilgit-Baltistan, Pakistan
The Chaqchan Mosque (; meaning “The Miraculous Mosque”) 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 Tibetan Buddhism to Islam. The mosque shares similar architecture as those built in the Kashmir Valley. It features a blend of Tibetan, Mughal and Persian styles of architecture.
History.
According to some sources the mosque was built by Mir Sayyid Ali Hamadani while other say on the arrival of Sufi saint Syed Nurbakhsh from Kashmir to Baltistan, the local ruling "Raja" converted to Islam and commissioned the building of the mosque in 1370 CE. However, the dating of the latter theory contradicts historical sources which suggests that the mosque was probably constructed more than two decades before the birth of Syed Nurbakhsh.
