Edirne, the second major capital of the Ottomans

The Beylerbeyi mosque, one of the oldest mosques in Edirne built in the first half of the 15th Century as part of a big Külliye, a complex of buildings centred on a mosque. It included a madrasah (Islamic school), a shrine, a bath, and a charity kitchen. It was badly damaged during the invasions of Russian and Bulgarian troops in the Balkan wars before World War I and restored several times. It has recently been restored and opened for services. The Edirne Beylerbeyi Mosque is an open-air gravestone museum reflecting different eras of Ottoman rule.
