Edinburgh Castle sits atop an ancient volcanic plug composed of basalt. This volcanic plug was a perfect vantage point for royalty wishing to oversee their realm. The city of Edinburgh is surrounded by seven such volcanic plugs -- all approximately 350 million years old. Archaeological excavations suggest that this site was inhabited as early as 850 BC. Edinburgh Castle was associated with monumental Scottish battles throughout the medieval period. Because its strategic geography permitted a 360-degree view for miles, it was nearly impossible for enemies to sneak up and attack the castle fortress. It makes sense that commoners wanted to live close by this stronghold. Thus, the city of Edinburgh rose around its famous castle. Photo taken on July 29, 2012.
