Brora Y Station
The building was built for the General Post Office and completed by 1939. During the Second World War it operated as a Y-station collecting information for analysts at Bletchley Park. Unlike other Y stations Brora did not close after the War but continued as a Cold War monitoring station under the aegis of Government Communications Headquarters until it closed in 1986.
