Portland Breakwater Lighthouse

The Portland Breakwater Lighthouse stands at the southern end of the north-east breakwater in Portland Harbour, Isle of Portland, Dorset. It is a white hexagonal cast-iron structure built in 1905 by Chance Brothers. The lighthouse originally showed a white flash every five seconds with a visible range of 16 miles. A fog bell sounded once every ten seconds in poor visibility. The light was first powered by oil, then gas, and now uses an LED lamp. The lighthouse was managed by Trinity House until automation in the late 1960s. Three resident keepers once lived nearby, one of whom recalled climbing the tower every two hours to wind the lens and pump oil. The breakwater was shared with about a million rats, which fled when torchlight appeared. Ownership later passed to Portland Port Ltd after restoration in 1995. A further restoration took place in 2016, and the original optic is now displayed in Weymouth Museum. Visitors find the lighthouse surrounded by defensive buildings such as pillboxes. It continues to guide boats with a white flash every ten seconds. The nearby breakwater offers views of Portland Harbour and the surrounding coastline. The former keepers’ dwelling remains on the breakwater, adding to the site’s history. The lighthouse’s restored structure and modern light stand as a practical aid to navigation.
