Porlock Weir, about 1.5 miles west of the inland village of Porlock, Somerset, England, is a small settlement around a harbour. Porlock means place of the port and Porlock Weir is its harbour. Weir refers to salmon stakes and traps that were situated along the shore. It is a popular visitor attraction.
Many cottages date from the 17th century, including the Gibraltar Cottages which have been designated by English Heritage as a grade II listed building.
Like most ports in West Somerset, the harbour is tidal and is home to a small flotilla of yachts and is visited by many more in spring and summer. The port has existed for more than a thousand years. The Anglo-Saxon Chronicle reports that in 1052 Harold Godwinson came from Ireland with nine ships and plundered the area and before that in 866 AD it was raided by Danes. In the 18th and 19th centuries coal from South Wales was the main cargo and in World War II pit props cut in local forests were the return cargo.
