A mosque in a Byzantine dungeon — tradition says the Prophet's companions sheltered here during the 7th-century siege

A mosque in a subterranean Byzantine vault near the Galata Bridge — originally part of a castle dungeon. Scognamillo notes this is where tradition claims the Prophet's companions Veysel Karani and others sheltered during the first Arab siege of Constantinople. Dark, atmospheric, and deeply spiritual — a place of pilgrimage that most tourists walk right over without knowing.
