Description : Khania Dighi Mosque also called Rajbibi Masjid, is located on the western bank of Khania Dighi, which is about a quarter mile away from the high mud wall of the ancient city of Gaur on the west in Nawabganj district. The building is now in a good state after thorough repairs undertaken by the Directorate of Archaeology department, Bangladesh. The mosque is not dated by any inscription although there is an epigraph over the central mihrab containing only verses from the Quran. But on stylistic ground it has been assigned to the later Ilyash Shahi period, say around 1480 AD. Chapai Nawabganj, Bangladesh. (Source-Banglapedia)
