Napoleonic Telegraph Tower

Built in 1809, the Telegraph Tower was part of a short-lived but crucial communication network used to report on the movement of French shipping around the Channel Islands. Designed to relay signals between Alderney and Sark, it remains the only building of its kind in the Islands, offering a unique glimpse into the island’s strategic importance and early optical telegraphy.

Now carefully restored and repurposed, the Telegraph Tower serves as a heritage site celebrating Alderney’s military and maritime past, with engaging displays on early signalling technology, the history of the tower, and its role in the island’s defences.

Open daily from 10am to 4.30pm.
