The Izzeddin Fortress is an Ottoman fortress in Souda Bay. It was established by the Ottomans in 1872. Already under the Cretan State (1898–1913) it was used as a prison, and continued so when Crete passed under Greek rule, until 1950. It was particularly notorious as a site of imprisonment for political prisoners, especially during the dictatorship of Theodoros Pangalos (1925–26) and the Greek Civil War.
