The ancient city was built, according to tradition, by the hero Alalkomenes. It was located between the cities of Aliarto and Koronia, southwest of Lake Copaida. It was known from the sanctuary of Alalkomenio, which was dedicated to goddes Athena. According to the tradition of the region, the great goddess had been born there and for this reason it was considered as a sacred city. Today in the place of the ancient Alalkomenes there is a small settlement with the same name.

The railway station of Alalkomenes was inaugurated in 1904 and was built by the "English Company of Lake Copaida" which was responsible for the drainage of the lake and has been classified as a preserved monument. The station is still in normal operation today and serves the town of Agios Georgios. The settlement of Agios Athanasios is located nearby on the plain.
