The Archaeological Museum of Astros is housed in a 19th century building, which was formerly used as a school (Karytsiotis school). After the necessary alterations and restoration works, the building, that follows the local traditional architecture, opened as a museum in 1985.
The Museum collections include :
- Architectural parts from Herodes Atticus villa
- Archeological Finds, mainly pottery of Hellenistic cemeteries.
- Small objects and coins from different parts of Kynouria.
- Signs from various positions of Kynouria.
