Kritsa (Greek: Κριτσά) is one of the oldest and most picturesque villages in Crete, Greece, built amphitheatrically on a rock hill, named Kastellos, surrounded by olive groves, at an altitude of 375 m. It is part of the municipality of Agios Nikolaos. During the Middle Ages, it was thought to be the largest village in Crete. Kritsa has been destroyed many times during the last centuries because it participated in all of Crete's revolutions.
