The Masjid al-Qiblatayn is a mosque in Medina believed by Muslims to be the place where prophet Muhammad received the command to change the Qibla (direction of prayer) from Jerusalem to Mecca.

The main prayer hall adopts rigid orthogonal geometry and symmetry which is accentuated by the use of twin minarets and twin domes.  The prayer hall consists of a series of arches which support barrel-vaults running parallel to the qibla wall. These vaults are interrupted by two domes which establish an axis in the direction of Mecca. The main dome to the south is raised on a drum of clerestory windows which allow light to filter into the interior directly above the mihrab. The second, false dome is linked to the first by a small cross-vault to symbolise the transition from one qibla to another. Below it, a replica of the mihrab found in the lower chamber of the Dome of the Rock in Jerusalem reminds onlookers of the oldest extant mihrab of Islam. Externally, the architectural vocabulary is inspired by traditional elements and motifs in a deliberate effort to offer an authentic image for an historic site.
