Layers of time

Edinburgh Castle overlooking a busy Grassmarket. Castle Rock, on which the castle sits, is a volcanic plug estimated to have formed 350 million years ago. This strategic strong point has been used as a place for fortresses since the Iron Age. The Castle was built in 1103, while the Grassmarket area dates back to the 1300s and is a UNESCO World Heritage site.
