Verla

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.

==Description== Verla is a typical example of a late-19th-century wood-processing mill village. The mill owner's residence, made out of wood, and the surrounding park are located on the western side of the river along with the factory buildings, and the workers' houses are arranged in a regular pattern on the eastern side. Most of the factory buildings are made out of red brick, and despite their somewhat outdated Neo Gothic style, they were technologically advanced for the time. These include the mill, the drying-plant, a flour mill and a few storehouses. Along the river, there are three power plants, constructed in the 1920s, 1954 and 1995. Prehistoric rock art (roughly 6,000 years old) was found on the eastern side of the river, depicting elk, humans and geometric patterns in red ink.
