PK Porthcurno – Museum of Global Communications
PK Porthcurno – Museum of Global Communications is one of Cornwall’s most surprising heritage sites, revealing how a quiet valley once became the centre of a global network. From 1870 onward, Porthcurno served as the landing point for undersea telegraph cables that connected Britain with India, Australia and Africa, making it one of the world’s most important communication hubs. Inside, visitors can explore the original underground tunnels built during the Second World War to protect the telegraph station. These atmospheric spaces now house interactive exhibits showing how messages once travelled across continents in minutes. Working equipment, Morse keys and early teleprinters demonstrate the evolution from cable telegraphy to modern digital communication. One of the most interesting features is the Cable Hut, where the historic undersea cables still emerge from the beach. The museum also displays rare engineering tools, training materials from the Porthcurno engineering school and stories of the global workforce who kept the network running. Outside, the valley’s landscape adds to the experience, reminding visitors how a remote Cornish village helped shape worldwide connectivity.
Porthcurno United Kingdom
PK Porthcurno, also known as the Museum of Global Communications, is located in the small coastal village of Porthcurno in west Cornwall. The museum sits in a peaceful valley just above the beach, on the site of the historic telegraph station that once connected Britain to the world. From 1870, Porthcurno was the landing point for undersea telegraph cables linking the UK to India, Australia, and beyond. During World War II, secret underground tunnels were built here to protect vital communications. Today the museum explores the story of global communication, from Victorian telegraphy to modern satellites and the internet. Exhibits include working Morse code stations, wartime coding equipment, and interactive displays about undersea cables. You can also tour the World War II tunnels and see the equipment that kept messages running during the war. What to see nearby: The museum is only a few minutes’ walk from Porthcurno Beach, a sandy cove with turquoise water framed by cliffs. Above the beach sits the famous Minack Theatre, an open air theatre carved into the granite cliffside with stunning sea views. The South West Coast Path passes through Porthcurno, offering coastal walks to Logan Rock and Porthgwarra. A short drive away are the fishing village of Mousehole and the harbour town of Penzance, with access to St Michael’s Mount.
