Barka in May 2014; Some definition to the extent of wall removal..It appears that something like 300 to 500 metres of outer wall plus at least two turret instalations (the outer wall thickness several feet thick and perhaps 10 feet high) has been incorporated into other buildings adjacent to the fort and may even have been co-opted into actual main fort extensions and repairs.
Also showing the slot down which boiling hot oil was poured turning the attackers into human toffee apples !
