The Varvakeio High School is a public Greek junior high school and high school located in Psychiko. It was founded by Ioannis Varvakis, who donated a big part of his fortune to the state, in order to build a public, fee-less high school. The realization of Varvakis' dream came true after his death as the building was opened in 1860, initially across from the present-day Varvakios Agora. Badly damaged in the civil war, the original Panagis Kalkos-designed building was demolished in 1955 or 1956. The school moved several times before settling on its current location in Psychiko in 1983. Originally all-male, the school became co-ed in 1979.
