Our hotel was located close to Greyfriars church. The church itself isn't that impressive, but the graveyard around it is very old and odd if you compare to what you normally see in other countries.
Lots of graves and tombs decorated with skulls, bones and other things that look macabre.
Everything that could be considered as haunted is also very popular in Edinburgh. One section of the graveyard is only open during night time when a haunted tour goes there.
