Porlock Weir lies about 1.5 miles west of the inland village of Porlock in Somerset, England. It is a small settlement around a harbour. Porlock means place of the port and weir refers to salmon stakes and traps that were situated along the shore. Many cottages date from the 17th century, including the Gibraltar Cottages which have been designated by English Heritage as a grade II listed building.
The pebbled beach at Porlock has a steep slope and a large tidal range due to the narrowing of the Bristol Channel. To prevent erosion and drifting the beach has many timber groynes all of which have numerous pebbles wedged into them by the force of the waves.
