Verla at Jaala, Kouvola, Finland, is a well preserved 19th century mill village and a UNESCO World Heritage Site since 1996. The first groundwood mill at Verla was founded in 1872 by Hugo Nauman but was destroyed by fire in 1876. A larger groundwood and board mill, founded in 1882 by Gottlieb Kreidl and Louis Haenel, continued to operate until 1964. The historical paper mill turned museum of board mill technology. The historical machines were preserved in their places (except for several pieces brought from other buildings), so a guided tour to the mill follows the technological process from timber cutting and pulp production to board drying, sorting, and packing. ==Gallery== Historical equipment in the museum.
