Pyrgos (Greek: Πύργος Βοιωτίας) is a small village in Boeotia, possible site of Homeric Nisa (Iliad 2.508). ^[1] It is named after a ruined medieval tower, with a notable Mycenaean element, that overlooks the village from a nearby hill. The hill is dedicated to Aiya Marina Pyrgos, or St. Marina of Pyrgos. The town forms part of the municipality of Orchomenos.
