In 1855, Laconia was incorporated as a town from land in Meredith Bridge, Lakeport, Weirs and part of Gilmanton. The name was probably derived from the old Laconia Company, formed by Captain John Mason and the Masonian Proprietors to sell parcels of land during the colonial era. The Great Fire of 1860 destroyed most of Main Street from Mill to Water streets, followed by the Great Lakeport Fire of 1903, a blaze so fierce that fire companies were brought by train from as far away as Dover. Laconia was incorporated as a city in 1893.
