Castles of the British Isles
The British Isles have a rich history of castles, and the exact number can vary depending on how one defines a castle. However, it is estimated that there are thousands of castles in the British Isles, encompassing England, Scotland, Wales, and Northern Ireland.
England alone is known to have had around 1,500 castles, although not all of them are still intact. Scotland also boasts a significant number of castles, with estimates ranging from 1,200 to 2,000 castles, including both intact structures and ruins.
