Just 5 minutes walk from the Treehouse through the old village of Ermioni, there is the Museum of History and Folklore, which is housed in a typical unique building-style of a traditional Ermioni house. This house, was built in the 18th Century but in recent years was carefully restored and is used as the Ermioni Museum of History and Folklore.
It is situated in the centre of the old village, next to the 9thC Byzantine church of Taxiarches (also worth a visit). The Museum is open every Saturday and Sunday throughout the year and every day during August. In the summer from 19:00 to 21:00 and in winter from 17:00 to 19:00.
