Rathcroghan
archaeological site
Rathcroghan (Irish: Ráth Cruachan, meaning 'fort of Cruachan') is a complex of archaeological sites near Tulsk in County Roscommon, Ireland. It is identified as the site of Cruachan, the traditional capital of the Connachta, the prehistoric and early medieval rulers of the kingdom of Connacht. Rathcroghan is one of the royal sites of Ireland. The ritual landscape extends over 6 square kilometres (2.3 sq mi) and consists of over 240 archaeological sites, 60 of which are protected national monuments. According to National Geographic, the site may be "Europe's largest unexcavated royal complex".
The monuments range from the Neolithic (4000–2500 BC), the Bronze (2500–500 BC) and Iron Ages (500 BC – 400 AD), to the medieval period. These monuments include burial mounds, ringforts and medieval field boundaries amongst others. The most prominent of these are the multi-period Rathcroghan Mound, the Oweynagat cave, the Mucklaghs (a set of linear earthworks), and the Carnfree medieval complex.
There are many historic references to Rathcroghan (Ráth Crúachan) recorded in early medieval manuscripts, including the 12th-century Lebor na hUidre. Rathcroghan is recorded as the location of one of the great fairs of Ireland, as well as being one of the island's three great pagan cemeteries.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q1009358. VIAF identifies the subject as 248344770. Authority coordinates are 53.802, -8.304. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
