The Marconi Company built a large high-powered Long Wave Wireless Telegraph transmitting station near the village in 1914 which worked in association with its receiving station at Tywyn. The station initiated commercial transatlantic wireless service from London to New York in 1920. It replaced Marconi's transatlantic wireless service from Clifden, Ireland to Canada, after the Clifden station was destroyed in the Irish Civil War in 1922. The building is now used as a climbing centre.
