1. It was once a major “sardine capital”
In the 18th century, Port Isaac was at the heart of Cornwall’s pilchard (sardine) industry. Huge shoals would arrive offshore, and entire teams worked to catch, salt, and export them across Europe—especially to Mediterranean countries.
2. It became a global TV icon overnight
The village is the real-life setting for the hit series Doc Martin, where it’s fictionalised as “Portwenn.”
Filming transformed the village into an international tourist destination almost overnight.
3. A local singing group became international stars
The sea-shanty group Fisherman’s Friends started as a group of local fishermen singing on the harbour.
They later signed a major record deal and even inspired a feature film—without ever giving up their day jobs initially.
4. It’s one of the most “authentic” preserved fishing villages in England
Because railways never reached Port Isaac, it avoided Victorian industrial expansion.
That accident of geography helped preserve:
Narrow medieval lanes (“drangs”)
Original stone cottages
The historic harbour layout
5. Its streets are so narrow cars can get stuck
The village includes one of the narrowest streets in Britain—Squeezy Belly Alley.
Modern cars often struggle (or fail) to pass through, which is why much of the village is effectively pedestrian-only.
6. It had a quiet smuggling past
Like many Cornish coastal villages, Port Isaac was involved in smuggling during the 18th century.
Nearby Port Gaverne was especially useful—its quieter cove made it perfect for landing contraband like: Brandy, Tobacco, Tea
Hidden storage spots and caves along the cliffs helped keep goods out of sight.
7. Fishermen used a “huer” to spot fish from cliffs
Before modern technology, a lookout called a “huer” stood on the cliffs scanning the sea.
When pilchards were spotted, they would shout and signal boats below using branches.
This system required incredible eyesight and coordination—and was vital to the village economy.
8. The harbour is deceptively dangerous
Despite its beauty, the harbour at Port Isaac is notoriously tricky to enter: Narrow entrance. Strong Atlantic swells. Sudden weather changes
This is why lifeboat services (linked to the Royal National Lifeboat Institution) have been so important here.
9. Locals historically spoke Cornish, not English
Centuries ago, everyday life in Port Isaac would have been conducted in the Cornish language, not English.
Although it declined by the 18th century, elements of Cornish survive in: Place names, local expressions, the village name itself (Porth Izzick)
10. Filming almost didn’t happen
When Doc Martin first chose Port Isaac, there were concerns from locals about disruption.
Now, it’s a major part of the village economy—but:
Filming still requires careful coordination
Some residents have mixed feelings about tourism levels
