Rathcroghan (Rath Cruachan – The Fort of Cruachan) is the oldest and largest unexcavated Royal Site in Europe. It is known as the Sacred Capital of Connacht, and is the location where the festival of Samhain (Halloween) is said to originate. The Rathcroghan Visitor Centre, home to interpretative rooms and a museum, is located in the medieval village of Tulsk, Co. Roscommon.
The Rathcroghan landscape boasts over 240 identified archaeological sites, contained within an area of 6.5km², ranging in date from the Neolithic Period (c. 3500 BC) through to the late Medieval period — a staggering span of over 5,500 years. It holds some 28 identified burial mounds from the Bronze and Iron Age, numerous ringforts, standing stones, linear earthworks, stone forts, a great Iron Age ritual sanctuary, and even a Gate to Hell — in truth, an archaeologist’s dream.
