where is the location that doc martin is filmed?
âPortwennâ is the fictional village and the main location for Doc Martin. An important backdrop and character in the show, Portwenn is actually played by the beautiful and historical fishing village Port Isaac, in North Cornwall, England. Doc Martin has been filming in Port Isaac since the series first episode in 2004, and has continued to film there every alternative year since. Filming happens every second year to give the residents a break, as the filming process can be quite disruptive on the village.
