Istanbul / Rumelihisarı

Bosphorus views from Rumeli Fortress

Sultan Mehmed II had this fortress built between March and August 1452 to control ships on the Bosphorus; its three towers stand 21 to 28 metres tall, and viewing terraces look out over the strait. Ottoman cannons, cannonballs and the Golden Horn chain are on display. Closed on Mondays; expect slopes and steps.
