Scotland is a mountainous country located in the north of Great Britain. In 1707, Scotland united with England to form Great Britain. Scotland is divided into two main areas - the mountainous Highlands and the more industrialized Lowlands. Some key aspects of Scottish culture include the bagpipe as the national musical instrument, haggis as a traditional food made from sheep organs, the kilt as the national dress for men, clan systems organized by family names and associated tartan patterns, and Highland Games competitions featuring bagpipes, dancing and strength events. Scotland is also known for its many lakes called lochs, including Loch Ness which is famous for the legend of the Loch Ness Monster.
