Port Isaac (Cornish: Porthusek) is a small and picturesque fishing village on the Atlantic Coast of North Cornwall, United Kingdom. The nearest towns are Wadebridge and Camelford, both ten miles away in opposite directions. Port Gaverne, commonly mistaken to be part of Port Isaac, is a hamlet that has its own individual history. Since the 1980s the village has served as backdrop to various TV productions, and most recently the ITV series Doc Martin. The meaning of the name Porth Izzick (modified in English spelling) is the "corn port," indicating a trade in corn from the arable inland district. Port Isaac viewed from the West.The Port Isaac pier was constructed during the reign of Henry VIII. The village's central precinct dates from the Eighteenth and Nineteenth centuries, from a time when its prosperity was tied to local coastal freight and fishing. The port handled cargoes such as coal, wood, stone, ores, limestone, salt, pottery and heavy goods which were conveyed down its narrow streets. Fishermen still work from the Platt, landing their daily catch of fish, crab and lobsters. The Port Isaac lifeboat station was established in 1869 following the delivery of two lifeboats called Richard and Sarah. The former boathouse is now the building called the Post Office. In the early 1960s the Royal National Lifeboat Institution introduced the Inshore Lifeboat, and in 1967 the Port Isaac Station reopened with a new class D inshore lifeboat. Since that time, the lifeboat has responded to more than 550 calls, in the process saving more than 140 lives. Today, Port Isaac's crew and shore helpers man the station twenty-four hours a day, 365 days a year, providing full coverage of Cornwall's north coast. Despite its isolation the village has had several visits from celebrities. The BBC series Poldark (1975-77) used locations in the area; the BBC drama serial The Nightmare Man (1981) was filmed in and around the village, which doubled for a Scottish island and it was a location for the film of Oscar and Lucinda (1997). The local village hall has been decorated by the team of DIY SOS, and to date, four seasons of the ITV series Doc Martin have been filmed there although the village has a fictional name of "Portwenn." Saving Grace, a successful comedy film, was filmed in and around the village. In October 2005, the village was again used for the backdrop to the television production of Rosamunde Pilcher's The Shell Seekers. Filming took place in the village for a week with the production's star, Vanessa Redgrave, filming many of her scenes in the main street. The filming of the third series is currently taking place.
