This place has all the makings of a spectacular haunting. It’s built on the site of a 14th-century abbey, which was itself built on top of a Druid temple (a modern shrine to the Egyptian Goddess Isis lies in the basement). And it certainly looks the part—the rambling, 17th-century crenelated manor house is overgrown with vines that turn blood-red in the fall. It should come as no surprise then that the castle claims to be the most haunted building in Ireland. The owners say it is plagued by the ghosts of druids who cause mists in the fields and showers of blood. Other than that, it’s very nice. The interior can only be seen by guided tour, which includes areas that were closed until recently, such as the old kitchens and drawing room. The gardens are beautiful—many of the plants date back to the 18th century—and the unusual 17th-century water features have been restored to working condition. Don’t miss the walking path guarded on either side by ancient yew trees. An adventure playground keeps little ones busy. If you’re not afraid of ghosts, the castle offers bed-and-breakfast and self-catering accommodations in the elegant Georgian gatehouse; e-mail for prices and information.
