The economy was traditionally based on the offshore fishery and today Lunenburg is the site of Canada’s largest secondary fish-processing plant. The town flourished in the late 1800s, and much of the historic architecture dates from that period.
In 1995, UNESCO designated it a World Heritage Site. UNESCO considers the site the best example of planned British colonial settlement in North America, as it retains its original layout and appearance of the 1800s, including local wooden vernacular architecture. UNESCO considers the town in need of protection because the future of its traditional economic underpinnings, the Atlantic fishery, is now very uncertain.
