andrew petersen, an archaeologist specialising in islamic architecture, surveyed the mosque in 1994. he found that the present mosque, built in the 1980s, encased the old building. the old part is the prayer hall, has an entrance to the north. this hall is square, covered with a dome. the dome rests on large squinches, which are supported by corbels. according to petersen, the domed prayer hall is consistent with an 18th-century construction date.
