English: Culmstock: Culmstock Beacon. This stone hut stands 250 m above sea level, close to a triangulation pillar and on the edge of the Blackdown Hills. It partially encloses a pole-beacon which was a communications signal ready for use when the Spanish Armada was sighted in the English Channel in 1588. Fires on the coast would be lit and then one by one a network of fire beacons set ablaze. This was the signal for all able-bodied men to assemble at their local church, await instructions and arm themselves. This is possibly the only beacon hut in the country to survive in its original form. It linked with others at Holcombe Rogus, Upottery and Blackborough. This slit window allowed observers to watch for a light at Upottery beacon. Looking west-north-west.
