Mosque of Tzistarakis

Historic Building in Monastiraki & Psyrri

Built in 1759, this building on the south side of Monastiraki is one of few surviving examples of a tzami (mosque) in Athens. It has not functioned as a mosque since Independence, except to cater to King Saud of Saudi Arabia when he visited in 1966. It's maintained by the Museum of Greek Folk Art, nominally to house its collection of traditional Greek ceramics from the early 20th century, but its 'temporary' closure, since 2015, seems chronic.

Still, at time of research, the museum was again making changes, so it's worth checking to see if it has reopened.
