Ross CastleRoss Castle
This 5-bedroom stone castle, built in 1536, is now run as a B&B. But beware: Guests often wake at night hearing voices and doors banging and shutting on their own. Paranormal believers say the spirit of an English lord’s daughter haunts the castle. So does the ghost of Myles “The Slasher” O’Reilly; the Irish folk hero spent his last night here before dying in battle, in 1644. 960 1280
Glasnevin Cemetery, DublinMore than 1.5 million people are buried in Dublin’s Glasnevin Cemetery, so tales of spooky ghosts shouldn’t come as a surprise. But it’s the story of one Newfoundland dog that steals the show. When his master died, the faithful canine companion refused to leave the gravesite, eventually starving to death. The dog’s apparition has been spotted at the tombstone. 960 1280
Loughcrew, Neolithic CemeteryThe Loughcrew Cairns are passage tombs, built 5,000 years ago. The Irish name for the cairns is Sliabh na Cailli, or “the Hills of the Witch.” Legend has it that a witch jumped from one hill to the next, dropping stones from her apron to form the cairns. 960 1280
