What rock is Edinburgh Castle made of?
dolerite

How was Edinburgh Castle rock formed?
The igneous rock intrusion, now known as Castle Rock, was formed by volcanic activity millions of years ago. This plug was more resistant to erosion by glaciers at the last glacial maximum in comparison to the surrounding bedrock, leaving the famous defensive site we know today.
