Arthur's Seat

Both Arthur's Seat (on the right) and Salisbury Crag (on the left) are contained within the city of Edinburgh, Scotland. Arthur's Seat is the plug of an underwater volcano which erupted in the Carboniferous Period about 335 million years ago. Salisbury Crag is a classic crag and tail where glaciers have left a tail of sediment extending towards Arthur's Seat to the right of the crag in the picture above. No other European city has at its heart such a splendid semi-natural park such as Holyrood Park.
