Fort Roupel

Fort Roupel (Greek: Οχυρό Ρούπελ) is a fortress at the north border of Central Macedonia, Greece, built-in 1914.

It became part of the fortifications of the Metaxas Line in the 1930s and became famous for its defence during the German invasion of Greece in April 1941.

This act led to the outbreak of a revolt of Venizelist Army officers in Thessaloniki and the establishment of the Provisional Government of National Defence under Entente auspices there, opposed to the official government of Athens and King Constantine I, cementing the so-called "National Schism".

The fort also became famous during World War II, when the advance of the German armies on that front sector was halted here.

For three days, the fort held out against German attack and was only abandoned by its men after the surrender of the Greek army in Thessaloniki.
