An Bang - aka City of Tombs, City of the Dead or City of Ghosts.
This is an enormous cemetery made up of hundreds of tombs. All of them are massive and resplendent with coloured tiles, carvings, mosaics and pillars. An absolutely beautiful place very much 'off the beaten track'. Great place to stop on the Hue - Hoi An route and none of the tours go here that I know of.
