Eski Kahta (Kocahisar) & Yeni Kale
Nemrut Dağı National Park
About 5km from the bridge is a 1km detour to Eski Kahta . There was once a palace here, but what's now evident are the ruins of a 13th-century Mamluk castle, Yeni Kale (New Fortress). The castle was being renovated at the time of writing and due to reopen in late 2012. After Yeni Kale, cross the Kahta (Nymphaios) River to see the old road and the graceful Seljuk Bridge .
