As you venture through the chalk limestone caves, the styles of the pillars tell you in which era the sections were quarried - Roman, Saxon and Norman all feature.
You can find Beer Stone in almost every church in East Devon, and it's also been used in Exeter, Winchester, St.Paul’s and Norwich Catholic Cathedrals, Westminster Abbey and the Tower of London.
