POLDHU is a small coastal area on the Lizard Peninsula in Cornwall, best known for both its scenic beach and its role in the early history of radio communication.

🌊 Poldhu Cove
* A sheltered sandy beach popular with swimmers and surfers

📡 Historic significance
Poldhu is famous as the site of pioneering wireless experiments:
