The town of Kongsberg stands 56 miles west of Oslo, in a hilly rural area along the valley of the river Numedalslågen. It has a heritage as an armament manufacturing and silver mining centre but today is mainly involved with high-tech industries. Visitors who hire a car in Kongsberg will soon note that it also stands at the major junction of the E134 heading to Oslo and Rv4 north to south route. To the south you'll find the Labro museum complex alongside a waterfall. There are museums about roads, hydroelectricity, floating timber and waterways here. At Lagdal there'’s a more rural museum centre, including an open-air collection of historic farm buildings.
