Edinburgh's historic graveyards are tranquil green havens at the very centre of the city, and a key part of the UNESCO World Heritage Site. Greyfriars is perhaps the most famous, with its connection to 'Greyfriars Bobby' the loyal Skye Terrier. However the kirkyard was also the scene of one of the most important events in Scottish history, the signing of the National Covenant in 1638. In the Canongate kirkyard the economist Adam Smith is buried, along with 'Clarinda' the muse for poet Robert Burns. The tombs, memorials and headstones are pieces of art in their own right, often giving a fascinating insight into the lives of peoplehundreds ofyears ago. The famous author Robert Louis Stevenson found many sources of inspriation in Edinburgh's graveyards - we invite you to do the same.
