Scapa Flow in Scotland is surrounded by the Okrney Islands. It has more ship wrecks in one single place than any other location in the world. Scapa Flow is part of the united kingdom, english is the official language and Pounds Sterling the official currency. Scapa Flow has not always been part of the United Kingdom, but was part of Norway, and much of the influence of its viking history still remains.

The wrecks of Scapa Flow have a long naval history. After world war I the german high fleet was sunk by the germans (scuttled) so they would not then become the property of Great Britian. Fifty two wrecks were originally sunk, but over the years salvage operations have removed many and now only eight wrecks from the german high fleet remain. During world war II several boats were purposefully sunk in the passages leading into Scapa Flow. These blocking boats were sunk in order to hinder the germans from sneaking into Scapa Flow and attacking the british fleet.

Diving at Scapa Flow provides a smorgasboard of wrecks upon which to dive, not just the german high fleet, but the blocking boats and other vessels that have sunk over the years in Scapa Flows natural lagoon. Among the more popular dive sites are the german light cruiser The Brummer, the battleships Kronprinz Wilhelm, Markgraf, Konig and cruisers Dresden, Koln and the World War II cruiser Karlsruhe. Several Wrecks in Scapa Flow are designated war graves and cannot be dived. Scapa Flow also offers the ability to dive with seals.

Typical marine life includes seals, plumrose anemomes, cushion starfish, sand eels, brittle starfish, sea squirts, feather stars and sea urchins.
