The Environment Museum of Stymphalia is located in the mountainous area of the prefecture of Corinth, there where, according to mythology, Hercules confronted and slew the Stymphalian birds. Situated in the northeastern Peloponnese at an altitude of 600m, the plateau of Stymphalia is surrounded by the mountains of Zireia, Oligyrtos, Mavrovounio and Gravias, on the southern side of the prefecture of Corinth. The water basin of Stymphalia is considered to be the largest mountain lake of the Peloponnese, at the same time as being the Balkans' southernmost mountain wetland. Its main interest resides in the lake's rich organic world, as well as in the underground and visible ways along which the water circulates. The region's ecological value, centred on the lake and its rich forests, is confirmed by its inclusion in the European Network of Protected Areas NATURA 2000.

The aim of the Environment Museum of Stymphalia is to show the interdependence of humankind and Nature and their harmonious coexistence in the Stymphalia basin. The basic goals of the museological approach are to raise the public's ecological awareness and preserve the knowledge relating to the region's traditional technology. This objective is reflected museologically by the exhibition's development in two exhibition units: the first concerns the environment in this region, while the second marks the manner in which the environment influenced the development of human activity and in particular that of traditional occupations.

Various means of expression and audiovisual media are used to ensure a better understanding of the exhibition's content. Pictorial presentations refer to the objects' use and are accompanied by corresponding audiovisual material of an educational nature. The exhibition's goals are supported by models and interactive applications, digital representations and documentary films. Also, for the first time in Greece, an accessible cross-section of the lake in the Museum's interior offers the visitor the possibility of observing, first hand, some of the region's plants and fish.

The Environment Museum of Stymphalia also comprises a cafeteria and a gift shop, while its multipurpose hall offers the possibility of developing cultural actions in the provinces, namely by hosting temporary exhibitions and organizing cultural events.
