Mullagh Hill or Drumceatt Mound which is adjacent to the Roe Valley Radisson Hotel is referenced as a site having a long history of religious and mystical connections. It was the venue for a major event around 575 AD known as the Convention of Drumceatt, the site replacing Tara as a venue. This convention brought together civil and religious rulers of Ireland and Scotland and was attended by St. Columba. The meeting was called by the King of Ireland and acted as a forum where debates took place, alliances were forged, laws for a the rule in Ireland were established and policies formulated for relationships to other kingdoms. St. Columba has close links to the area, he was born near Gartan in Donegal and founded the first monastic settlement in Daire (now Londonderry or Derry).

A close friend  was St. Canice who was born a few miles outside Limavady at Drumramer, he is referred to as the patron saint of the Roe Valley. St Canice is credited with founding the monastery at Drumchose, the Parish Church of Faughanvale in Eglington is named after him. The area around Limavady and the Roe Valley is scattered with ancient cairns and artifacts. The famous Broighter Gold, named after the townland where it was found in 1896 by Thomas Nicholl while he was working the land, is an exquisite collection of finely worked gold. Incidentally, in 1996 the Mint produced a pound coin with the Broighter Collar stamped on it. The hoard consisted of a thick collar, a bowl, two necklets, two plaited wire chains and a model of a boat with eighteen rowlocks and fittings including a small spear. The collection dates to 3000 BC.
