Conducted tours by trained guides gives you an hour-long tour of this vast man- made complex of underground caverns created by centuries of quarrying the famous Beer Stone. The underground quarry first worked by the Romans, supplied stone for 24 cathedrals including Exeter and St. Pauls, parts of Westminster Abbey, the Tower of London, Hampton Court and Windsor Castle. Quarried by hand, the smallest blocks weighing 4 tons, the stone was carted on horse-drawn wagons and by barges from Beer beach to its destination, sometimes involving journeys of several hundreds of miles.
I would recommend wearing something warm, even in the summer…..they don’t get much sunshine down there!
