While not of great speleological significance, Oweynagat (‘Cave of the Cats’) I would argue, is one of the most intriguing archaeological monuments in Ireland. Today it feels hidden away and out of sight located as it is almost in the ditch of a modern field boundary. However, as a cave feature it is situated in one the most karstic regions of Ireland (that is, in County Roscommon) and as an archaeological monument it forms part of a complex of 50 archaeological monuments that make up the ancient pre-Christian Connaught royal site of Cruachán. It is therefore of special importance as a cultural adaptation of a natural geological feature.
One at the entrance reads ‘Fraech son of Medb’. Mebd likely refers to the Queen of Connaught, Maeve, whose bickering pillow-talk with King Ailill over cattle ownership lead to the attempted stealing of the Cow Of Cooley and the rise to prominence of the fearsome and brutal Cú Chulainn. Until recently, the cave was known as the entrance to the underworld where, at Hallowe’en each year, the cave served as a portal to and from hell.
The dry stone walls of the souterrain soon give way to very fine solid limestone walls which open into a long rift chamber. The rift passage form seems to be quite common in this area of Roscommon and there are a number of open similar passages recorded in the surrounding fields (Fenwick and Parkes, 1997) . These, however, are roofless and Oweyngat is by far the most impressive. While only 30m long the rift is quite impressive and the walls preserve a good degree of moonmilk calcite. For an easy to access spot, it is also relatively clean and undamaged.
NOTE: While this cave is very accessible and well worth a visit, please note that it is protected as a National (Archaeological) Monument as well as a protected habitat under Annex I of the Habitats Directive. It is great that such a monument is open to the pubic so please ensure that your actions here won’t lead to its damage and the inevitable gating of the entrance!
