The Rendell Forge is a small, one-room, one storey wooden blacksmith shop located in Heart's Content. The Rendell family had a long history of blacksmithing in the community. The first to arrive was blacksmith Charles Rendell, who moved to Heart's Content from Trinity, Trinity Bay, in the early 1800s to craft ironwork for vessels. In 1864–65, four Rendells were listed as blacksmiths: Charles, G., James, and John. The 1904 directory lists five: Giles, Tolson, Charles Sr, John, and John T. Ted Rowe writes,Descendants of Charles Rendell produced an unbroken line in the blacksmith trade in Heart’s Content for three generations. His four sons Charles, Giles, James and John all took up the trade. Son Charles was also Heart’s Content’s first constable, appointed in the 1830s, and was prominent in the Loyal Orange Association. Bela, son of Giles, operated this forge with his son Jim in the 1920s. When business fell off during the depression years Jim moved his family to Hants Harbour. In 1941 at the age of 60 Bela went to Scotland as a blacksmith with the
Newfoundland Overseas Forestry Unit. He returned to Heart’s Content at the end of the war and continued with the forge in the 1950s, turning out grapnels, horseshoes and custom ironwork. Following his death his son Ray worked the operation on a part-time basis.James Rendell (son of Charles Sr) moved to East Boston, Massachusetts, where he worked as a blacksmith, machinist, and businessman, and where he married Rebecca Rendell (née Pugh) of King's Road, St. John's on December 10, 1892. Some of the Rendell blacksmiths went to Gander to work on the building of the airport and town in the 1940s. The last of the Rendells to work in the forge, Ray, used the building until circa 1990. and children passed ownership of the building and the land on which it sits over to the Mizzen Heritage Society on 11 July 2006. == Demographics ==
