Greyfriars Bobby is the world-famous Skye Terrier who did not leave his masters grave for fourteen years. He and his master John Gray are buried in the kirk yard of the Greyfriars Kirk, the first church to be build in Edinburgh after the reformation. The graveyard includes impressive mausoleums, headstones and mortis safes to protect the dead against robbers selling the corpses to anatomists. The National Convenant was signed here in 1638. The martyrs' memorial stands for the convenanters who were imprisoned here. The kirk also offers Gaelic services.
