Coleraine County Derry.

Cúil Raithin
(Nook of the ferns)

The town of Coleraine lies on the River Bann, about 8 km (5 mi) from its mouth, the lowest point at which the river can be crossed. Its name is derived from the Irish Gaelic Cúil Rathain, meaning “ferny corner”. Coleraine has a small port, and is a centre for a road and rail network. A weekly market is held in the town.

The town was formally a centre of the linen industry, with spinning, weaving, shirt making and bleaching carried out. The town gave its name to half-bleached cloths for shirting which became known as “Coleraine's”. Industries present in the town today are light engineering and food processing, including the manufacture of Irish whiskey.
The University of Ulster's main campus is at Coleraine.

Some of the earliest evidence of human habitation in Ireland was discovered near Coleraine proving that the area has been populated for at least 9,000 years. In the Christian era there was a religious centre there, with a priory and a monastery. Mountsandel Fort was a Celtic stronghold, later occupied and strengthened by the Normans. City of London companies which were actively engaged in the Plantation of Ulster in the 17th century were largely responsible for developing the modern town. Coleraine District covers an area of 486 sq km (187 sq mi), and includes Castlerock, Portrush, and Portstewart.
