J.K. Rowling was living in Edinburgh when she wrote the first Harry Potter book. So it is to be expected that she set the wizard school, Hogwarts, in Scotland. A beautiful country, filled with mountains, lakes (lochs) and forests, it makes a wonderful setting for the magical castle that serves as boarding school for witches and wizards.
Scotland is part of the United Kingdom. The capital city is Edinburgh, an important historical, cultural and financial centre.
The flag of Scotland dates back to the 9th century and is one of the oldest national flags still in use today. It is known as the Saltire, or St. Andrew's Cross.
Children born with magical abilities are invited to attend Hogwarts School of Witchcraft and Wizardry to study subjects like Potions, Defence Against the Dark Arts and Charms.
Hogwarts is a castle built on a mountain near a loch in Scotland's Highlands. It is protected by magic, so no uninvited wizard or witch can Apparate inside the school. Only the headmaster can lift these powerful spells. The castle is not only protected from magical humans or creatures but is bewitched so that any Muggle seeing it thinks it is an abandoned and dangerous place.
