Known as the “Tzistarakis Mosque,” this is one of the few Muslim monuments remaining in Athens. Built in 1759 by the Governor, Tzistarakis, during the second period (1689-1821) of the Ottoman occupation, it has been rumoured that the lime used for its construction was procured by melting down a column from the Olympieion. But research has proved that a column from Hadrian’s Library was actually used. In the 20th Century, the mosque housed the Museum of Hellenic Folk Art.
Today it serves as an annex of this museum. It is remarkable that in 1966, the mosque was partially restored so that Ibn Saud, exiled, ex-monarch of Saudi Arabia, could perform his religious duties here.
