Rahmi M Koç Industrial Museum

Lonely Planet review

In the old Çengelhan the new Rahmi M Koç Industrial Museum is perfect for kids (and adults) who prefer a hands-on approach to staring at a bunch of pots behind glass, and has slightly less emphasis on transport than its original branch in İstanbul .

Walk straight ahead once you've entered the gate and you'll see, on your left, the citadel mosque, the Alaettin Camii, which dates from the 12th century but has been extensively rebuilt.

To your right a steep road leads to a flight of stairs taking you up to the Şark Kulesi (Eastern Tower), with panoramic city views. Although it's much harder to find, the tower at the north, Ak Kale (White Fort), also offers fine views. If you're coming up to the citadel along Hisarparkı Caddesi, look left about halfway up to see the remains of a Roman theatre from around 200 to 100 BC. Inside the citadel local people still live as in a traditional Turkish village, and you'll see women beating and sorting skeins of wool in the gaps between the inevitable carpet shops. As you wander about, you'll notice broken column drums, bits of marble statuary and inscribed lintels all incorporated into the mighty walls.
