Overview

Unearth fascinating objects and stories from London’s past in the UK’s first major exhibition dedicated to mudlarking.

Explore the hidden world of the mudlarks.

Twice a day, the River Thames dramatically recedes to expose a landscape unknown to most Londoners. Among the mud and the stones, the tides reveal remarkable objects from every era of London’s rich past.

The exhibition features over 350 mudlarked objects, from intimate personal items to historical relics, with many on display for the first time. Step into the shoes of a mudlark and explore the foreshore, uncover artefacts and learn how they identify and curate their personal collections.

The journey ends with a space for reflection on the mysteries of the moon and the tides that make mudlarking possible, leaving visitors with a powerful, contemplative memory of their time uncovering the secrets of the Thames.

Blending archaeology with contemporary art and digital experiences, Secrets of the Thames offers fresh perspectives on London and all its people – past and present.
