Kirkwall is the largest settlement and capital of Orkney, an archipelago in the north of Scotland with history tracing back to Norse times in the 11th century. With history such as this, ancient archaeological sites are the highlight of a visit. The most important monuments can be found at the Heart of Neolithic Orkney, designated a UNESCO World Heritage site. The Ring of Brodgar is one of the finest known truly circular Neolithic stone rings. Other sites that are fascinating to tour are Maeshowe, the Standing Stones of Stenness and the ancient Neolithic village of Skara Brae. For a completely different experience, dive the many shipwrecks at Scapa Flow, where the Germans scuttled their fleet after World War 1.
