Ertuğrul Tekke Mosque

The Ertuğrul Tekke Mosque is an Ottoman imperial mosque in the Yıldız neighbourhood of the Beşiktaş district of Istanbul, Turkey, built as part of a külliye, a complex that also holds a dervish lodge (tekke), a guest house, a türbe, a fountain and a library. Sultan Abdul Hamid II commissioned the complex and it was finished in 1887. It is dedicated to Sheikh Hamza Zafir, a Libyan Sufi who founded the Medeni branch of the Shadhili order, and it takes its name from Ertuğrul Gazi, the father of Osman I, and from the Ertuğrul Regiment of the palace guard. The mosque and the guest houses are wooden buildings in the classical architecture of the late Ottoman period, and the original architect is not known. After the sheikh died in 1903 his türbe was built beside the mosque by the Italian architect Raimondo D'Aronco between 1905 and 1906, with the library and the fountain added in the same expansion, all in the Art Nouveau style. The mosque and tekke were closed after tekkes were abolished in 1925, the guest houses served as a primary school, and the mosque was restored between 1969 and 1973 and again from 2008, reopening to the public on 21 May 2010.
