The King Mosque stands just inside the western gate of the castle walls, a low Ottoman structure with a single minaret and a shaded portico. It dates from 1492, built in the first decades after Elbasan came fully under Ottoman control, and it retains its original proportions even after restoration.
The interior is plain by the standards of later Ottoman mosques — whitewashed walls, a simple mihrab, and light from high windows. Non-Muslim visitors are welcome outside of prayer times; it is customary to remove shoes before entering. The courtyard fountain and the old plane trees around the entrance make it a pleasant place to pause.
