The Trinity House Obelisk, also known as the Trinity House Landmark, is a 19th-century obelisk located at Portland Bill, on the Isle of Portland, Dorset, England. Built as a daymark, it has been Grade II Listed since 1978.[1]
The obelisk was built in 1844 to warn ships off the coast of Portland Bill. It stands at the southern tip of the Isle of Portland, acting as a warning of the low shelf of rock extending 30 metres south into the sea.[2] The obelisk is made of Portland stone and is seven metres in height. It is inscribed "TH 1844" on its north face.[1] The monument was saved from threatened demolition in 2002 after Trinity House deemed it too expensive to maintain.[3][4]
