Cavity Detection – Lost Places Beneath your Feet

Treasures of the Old World hidden in chambers and vaults

Treasures of the nobility such as the riches of the Wettins or the crown jewels of the British monarchy were and are still are kept in treasure chambers. The riches of the church were also hidden in vaults and crypts under chapels, churches and cathedrals.

The Cologne Cathedral (Germany), the Green Vault in Dresden (Germany), cathedral treasure chambers in Germany, Liechtenstein and Italy as well as the Tower of London (Great Britain) are just a few of the numerous treasure chambers in Central and Western Europe. Outside Central Europe, the treasures of the Topkapi Palace in Istanbul (Turkey) and the Moscow Kremlin (Russia) attract visitors. Many of the treasures are now part of the world cultural heritage and are partly open to the public.

Numerous hidden treasure chambers are still waiting to be discovered. Over the centuries, riches were hidden in underground vaults – sealed to protect them from plunderers or buried by natural events – and were forgotten gradually. Treasure hunters follow legendary myths and targeted clues with the aim of making the greatest find of their lives.
