The Classical Lyceum Anavryton (official name "Ethnikon Ekpaideftirio Anavryton", but commonly known as Anavryta) was an elite Greek lyceum (originally a boarding school only for boys) that was established shortly before the beginning of the World War II in 1940, in order to provide education to the members of the Greek royal family and notable Athenian families and reestablished after the war in 1949.
The school complex is located in the area of Maroussi, near Athens, in the middle of the pine forest of Anavryta, formerly the estate of banking magnate Andreas Syngros.
After the support of Constantine to the military junta in the early months of 1967 and with the public strongly opposing monarchy, a referendum vote established the system of presidential democracy and denounced the king in 1974.
However, in recent years the Anavryta experiment has been reinstated and the selective admission approach restored in 2013, when the Greek Government made it mandatory for students to pass written examinations.
Most of the original buildings have been closed and the school facilities, although in ideal surroundings, have been found under a recent research to be the worst in Northern Athens.
