Halloween at Kilronan Castle
Experience Halloween where it all began
Here in County Roscommon, Halloween has its roots in Samhain, the ancient Celtic festival marking the transition from summer to winter. Just a short journey from Kilronan Castle lies Rathcroghan, the ancient royal site of Connacht and one of Ireland’s most important prehistoric landscapes.
It was here, amid ancient monuments, myths and legends, that Samhain was celebrated more than 2,000 years ago. Nearby lies Oweynagat, the Cave of the Cats, a mysterious underground passage long associated with the Otherworld and the supernatural.
