Semaphore Tower is a unique remnant from the Napoleonic era, the Grade II* listed brick structure is the only surviving semaphore tower in Britain. It was once a cutting-edge building at the forefront of technology and design, a vital link in a signalling chain that transmitted messages from Admiralty House in London to Portsmouth Docks in just a few minutes.
