Cemetery, Graveyard, Necropolis, City of the Dead. Pretty much every fantasy city, town and village has such, and they have a great promise of adventure: Necromancers looking for bodies, haunts with unfinished business, buried treasures and even a whole unholy domain, especially at night time – as Necropolis and it's Dark Reliquary in Ptolus.
A classic theme in fantasy games, this cemetery terrain has gained some inspiration from Baldur's Gate II: Shadows of Amn and Montmartre cemetery in Paris. These terrains have often seen use in rpg's, and they really bring atmosphere.
