English: A stone building, a signal station, at Culmostock Beacon in Devon, UK, built in 1588 to enclose a wooden pole, which protruded through the roof to support one or more fire baskets. This is one of a chain of signal stations along England's southern counties - but the only remaining stone building - the purpose of which was to warn of the Spanish Armada being sighted. There is an adjacent Ordnance Survey (the UK's official mapping agency) trig point with the bench mark S.3745.
