WHAT LIES UNDERNEATH. A must do experience for locals and visitors alike. An impressive archaeological and architectural site created by unskilled workers using basic tunnelling/quarrying tools - they had no access to modern machinery. Enter a world of smallish tunnels and cathedral sized caverns. Our guides, Tony and Tom, are enthusiastic and are eager to impart as much of their knowledge to you as possible and are ably assisted by Laura in reception. Remember to give as generous a donation as possible to help them to continue with their work of excavating more areas of the site.
