Scotland is a country on the island of Great Britain in Western Europe that is part of the United Kingdom. Its only land border is with England, to the south. Its capital city is Edinburgh.
Scotland is the location of Hogwarts School of Witchcraft and Wizardry and the magical village of Hogsmeade. The more remote, mountainous terrain of Scotland makes it a more likely choice of place for an institution that must be disguised to keep it invisible to Muggles. Its location is unknown, though Hermione says it is close to Dufftown. Though it is more likely in the North West Highlands (probably Sutherland) due to the more isolated landscapes and the lack of nearby towns.
Scotland is one of the most frequent breakers of Clause 73 (this is the clause that ensures the secrecy of magical creatures) of the International Statute of Wizarding Secrecy of any nation. This is mostly due to the world's largest kelpie residing in Loch Ness.
The Banchory Bangers were a Scottish Quidditch team noted for their poor skills and post-match parties. After a match against the Appleby Arrows in 1814, the Bangers allowed their Bludgers to zoom off into the night, and set out to capture a Hebridean Black to be their mascot.
Creaothceann originated in Scotland, and is regarded as the most dangerous of all broom games. Creaothceann players were equipped with a broomstick and wore a cauldron strapped to their head. At the start of the game, a hundred rocks that had been charmed to float a hundred feet (30.48m) above the ground began to fall to the ground. The players then zoomed around the field, trying to catch as many rocks in their cauldrons as possible.
Rowena Ravenclaw was a witch of Medieval Times and one of the four founders of Hogwarts. She was noted for her cleverness and creativity, and was described by Xenophilius Lovegood as "beautiful." The Sorting Hat introduced her as “fair Ravenclaw, from glen,” suggesting she was from Scotland. (possible)
