Ballykelly contains some of the most interesting buildings erected in Ulster by the Plantation companies, being largely developed by the London Company of Fishmongers through the 18th and 19th centuries. It features Tamlaghtfinlagan Parish Church, built by Earl Frederick Hervey, 18th-century Bishop of Derry, amongst many traditional buildings. The Presbyterian Church, Drummond Hotel and North West Independent Hospital, were all built by the London Company of Fishmongers. The village enjoys views across Lough Foyle to Inishowen in County Donegal and is bordered by Ballykelly Forest which was the first State Forest in Northern Ireland. Although there are good health and educational facilities available, there is only a limited retail sector relative to the population of the village.
