Trinity House Obelisk, 19th-century maritime monument at Portland Bill, England
The Trinity House Obelisk is a stone monument on the coast near Portland Bill, at the southern tip of the Isle of Portland in Dorset, England. It is built entirely from local Portland stone and tapers upward to a pyramidal point.
Trinity House, the British authority responsible for lighthouses and sea marks, erected this obelisk in 1844 as a warning for ships approaching dangerous rocks south of Portland Bill. It is now a Grade II listed building, recognized for its historic value.
The obelisk stands along a stretch of coast that sailors and fishermen have used for generations as a reference point. Walking the coastal path today, it still reads as a working marker rather than a decorative feature.
The obelisk is reached on foot via the coastal path from Portland Bill, and there are no fees or restrictions to visit. The path can be uneven near the cliff edges, so sturdy footwear is a good idea.
The north face of the obelisk carries a carved inscription reading 'TH 1844', marking the authority that built it and the year of construction. Most visitors walk past without noticing it, as it faces away from the main coastal view.
