Bohus granite

Bohus granite (Swedish: Bohusgranit) is a type of granite found along the west coast of Sweden, in Bohuslän. In Norway, these are called Iddefjord granite (Norwegian: Iddefjordsgranitt), Østfold granite and Halden granite. A large quarrying industry has developed around them, mainly producing blocks. Large scale extraction begun in the 1840s and employment in the quarries peaked in the 1920s with over 7,000 people working in the industry. The rock is valued for its durability. In the first half of the 20th century, quarried Bohus granite was often transported on the Lysekil rail line. In Norway, Iddefjord granite is a relatively common rock in architecture, and many of the statues of Frogner Park in Oslo are made of it. Iddefjord granite is the official county rock of Østfold in Norway.
