Five of Edinburgh's historic graveyards which were added to a list of the 100 most endangered monuments in the world are now getting help. Heritage watchdogs and city council officials have formed an Historic Graveyard Trust to improve security,provide visitor trails and interpretation boards. The burial grounds within the city's World Heritage Site are said to be at risk of crumbling into disrepair. The Greyfriars,Canongate,Old and New Calton and St Cuthbert's graveyards are the final resting places of a number of world famous figures including economist Adam Smith,philospher David Hume, and poet Robert Fergusson. Fortunately many have already been transcribed by Scottish genealogists and family historians but their architectural and artistic value are equally worth preservation.
