Västerås is surrounded by pre-Christian sites. The most interesting and extensive is Anundshög, the biggest tumulus (burial ground) in Sweden, 6km northeast of the city. It has a full complement of prehistoric curiosities, such as mounds, stone ship settings and a large 11th-century rune stone. The two main ship settings date from around the 1st century. The area is part of the Badelunda Ridge, which includes the 13th-century Badelunda Church (1km north) and the 16m-wide Tibble Labyrinth (1km south).
