History of Kymenlaakso

Verla at Jaala, Kouvola, Finland, is a well-preserved 19th-century mill village. Situated along the northern Kymi River, the mill, nearby power plants, and residential houses were inscribed on the UNESCO World Heritage List in 1996 due to its testimony to the lumber industry in the 19th century and the lives of the industrial workers of that time.
