Lunenburg, is a Canadian port town in Lunenburg County, Nova Scotia.
Situated on the province's South Shore, Lunenburg is located on a peninsula at the western side of Mahone Bay. The town is approximately 90 kilometres southwest of the county boundary with the Halifax Regional Municipality.
The town was established during Father Le Loutre's War, four years after Halifax. The town was one of the first British attempts to settle Protestants in Nova Scotia and, as a result, the (Catholic) Wabanaki Confederacy raided the community nine times in the early years of the settlement.
The historic town was designated a United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Site in 1995. This designation ensures protection for much of Lunenburg's unique architecture and civic design, being the best example of planned British colonial settlement in North America
