Bash Tapia Castle is one of Mosul’s surviving historic fortifications, set on high ground above the city and the Tigris. Much of it is ruined, but the site still conveys the defensive importance of Mosul’s river position.
Conditions and access can change, so treat it as a place to ask locally about before visiting. For travellers with appropriate security context, the castle is a stark reminder of the layers of empire, conflict, and recovery visible across Mosul.
