In the 40 years between 1971 and 2011, Limavady's population nearly doubled. Limavady is within Causeway Coast and Glens Borough. From 1988 to 2004, a total of 1,332 dwellings were built in the town, mainly at Bovally along the southeastern edge of the town. The large industrial estate at Aghanloo is 2 miles (3 km) north of the town. Limavady and its surrounding settlements derive from Celtic roots, although no-one is sure about the exact date of Limavady's origins. Estimates date from around 5 CE. Early records tell of Saint Columba, who presided over a meeting of the Kings at Mullagh Hill near Limavady in 575 CE, a location which is now part of the Roe Park Resort. Gaelic Ireland was divided into kingdoms, each ruled by its own family or clan. In the Limavady area, the predominant family was the O'Cahans. Their mark is found everywhere in the town and surrounding area. O'Cahan's Rock is one of Limavady's main historical points. This is where, according to local myth, a dog belonging to one of the Chiefs jumped the river to get help from nearby clans after a surprise enemy attack. This gave Limavady its name, Limavady being the anglicised version of Leim an Mhadaidh, which means leap of the dog. This rock, along with other relics of Limavady's history, can be seen at Roe Valley Country Park. The town developed from a small Plantation settlement founded by Sir Thomas Phillips. In 1610 Sir Thomas Phillips was granted 13,100 acres of land at Limavady which included an O’Cahan castle. He commenced the building of the 'Newtown of Limavady' which was laid out in a cruciform road pattern. Newtown Limavady was incorporated, with the appointment of a Provost and 12 Burgesses, on 31 March 1613 with a charter granted by King James I.
