Little is known about the pre-Celtic peoples of this area, but the Coggalbeg hoard demonstrates their artistry. It was found in 1945 near Strokestown by a turf-cutter, and comprises a gold lunula (crescent moon shape) and two gold discs, all lightweight and suitable for personal ornament. The hoard was tucked away in a pharmacist's safe, until 2009 when the safe was stolen during a break-in. The thieves were only interested in ready cash and dumped the other contents into a skip in Dublin, but were spotted on CCTV. The police retrieved the hoard, which is now on display in the National Museum in Dublin and dated to 2000 BC.
By the early centuries AD the west of Ireland was populated by Celts in the Kingdom of Connacht, ruled from Cruachan, nowadays called Rathcroghan and with extensive remains. The area became christianized, and Coman Mac Faelchon built a monastery in the 5th century. The woods near the monastery became known as Ros Comáin, "Coman's Wood", hence Roscommon town. The native rulers were subjugated by King John in the 13th century, and the Tudors set out the county boundaries.
County Roscommon has low hills, mostly in the northeast towards Lough Allen, with Seltannasaggart reaching 428 m (1404 ft). The farmland is poor and drains east into the River Shannon and its loughs, which are navigable and form the natural boundary with Counties Leitrim and Longford. There's been little industry since a 17th / 18th century spell of coal and iron mining, and thus little to foster population growth or urban development. "Unspoilt" is how the County Tourist Agency pitches it. The region is collectively promoted under the brand "Ireland's Hidden Heartlands".
