The main dome has a diameter of 12 metres (39 feet) and is supported by eight internal buttresses.

The five small domes of the portico are supported by arches with marble columns.

The underglaze painted tiled panels have white thuluth lettering reserved on a dark cobalt blue background.

Above the mihrab is a larger lunette panel painted in cobalt blue, turquoise and dark olive green.

The purple colouring is characteristic of the 'Damascus' style of Iznik pottery but is unusual on tiles.
