Marconi-Kemp Plaque, St Lawrence's Church, Fort Road, Lavernock Point, Vale of Glamorgan 16 July 2025

            A bronze plaque in the enclosing wall of St Lawrence's Church commemorating the first wireless exchange over water in 1897 by Marconi and George Kemp, a Cardiff based Post Office engineer. Kemp set up a station on the island of Flat Holm in the Bristol Channel, with Marconi set up at Lavernock Point. After the success of this experiment, they set up a station at Brean Down, transmitting signals over 7.5 miles. As a result of this trial, Marconi went on to establish his Wireless Telegraph and Signal Company.
