About Us

PK Porthcurno is a museum that explores the story of how the world connects.

From 1870, when the first undersea telegraph cable came ashore here from India, to the arrival of fibre optics which carry virtually all our communications today, the sands of Cornwall’s most idyllic beach have hidden the world’s greatest communications secrets.

In its iconic white building just off the beach, PK Porthcurno is a celebration of the pioneering achievements of unsung heroes, and the power of human ingenuity in the quest to connect people and places. Here, we transformed the way the world connects. PK Porthcurno is for people who want to understand how a once uninhabited valley in Cornwall became the heart of worldwide communications, how it remains so today, and what might happen tomorrow.


By becoming a friend of PK Porthcurno, you are supporting vital projects including the conservation of our collection and historic listed buildings, our exhibitions and events, and our learning and public engagement programmes.

“We have designed our civilization based on science and technology and at the same time arranged things so that almost no one understands anything at all about science and technology.  This is a clear prescription for disaster”
