Kolmård Forest

Kolmård Forest lies on the boundary between Södermanland and Östergötland, to the north of the long inlet of Bråvik. This well-wooded upland region extends for some 100km/60mi from west to east. The rocks are mainly reddish gneiss, together with some red and black granite. Stone from here was used in the construction of the Parliament Building in Stockholm in the 19th century. There is also a certain amount of iron and copper in the area. The famous green marble found in the eastern part of the region was worked at intervals over a period of almost 300 years, from 1673 to 1960.
