The graceful Sultan Beyazıt II Camii (1486) is Amasya's largest külliye (mosque complex), with a medrese, fountain, imaret (soup kitchen) and library. The main door, mihrab (niche in a minaret indicating the direction of Mecca) and pulpit are made of white marble, and its windows feature kündekari (interlocking wooden carvings). It's surrounded by manicured lawns and is popular with locals.
In the mosque grounds is the small and rather eccentric Minyatür Amasya Müzesi , which is a near perfect recreation of Amasya in miniature. Use it to plan your route up to the castle and stay for nightfall to listen to the call to prayer. Children will love this one.
