A guided walk with mudlark Mark Sowden following the course of the Walbrook from Liverpool Street to the Thames.

The Walbrook is one of London’s lost rivers. Today it is enclosed in drains deep underground but it once flowed freely through the centre of Roman Londinium.

During the walk, mudlark and artist Mark Sowden will help you spot subtle clues in today’s urban landscape that allow you to pick out the course of the Walbrook.

You'll stop at various sites along the route where archaeological excavations have revealed evidence of the Walbrook and the ways past Londoners controlled and used the river.

Visual information including photographs from the archaeological digs, maps of Roman and medieval London and finds from the Thames foreshore will be presented along the route to evoke the lost landscape more fully.

Mark Sowden

Mark has been a mudlark on the Thames foreshore for eight years and many of his finds closely resemble those found on archaeological digs. It is even possible that some of the pottery he has found was made at a kiln site on the Walbrook.

Need to know

Please meet at the Bubble Bond public sculpture in front of 100 Liverpool Street 10 minutes before the start of the tour.

If the tide and weather allows, the tour will finish on the Thames foreshore. Accessibility may be difficult to participants with mobility issues. Please contact the Box Office with any questions or concerns.

Please dress appropriately for the weather and wear or bring footwear for walking and for the foreshore.

Please do not bring dogs or pushchairs.

Tours happen in a mixture of rain and shine, so don't assume that an event is cancelled because of a weather forecast.

In the event that we're forced to cancel, you'll receive a full refund.

As a rough guide, these are the main weather conditions where we may need to contact you:

  • snow and ice, making the ground treacherous
  • heavy fog, which severely restricts visibility of the group by our staff
  • lightning
  • amber weather warnings
  • yellow weather warnings, as although tours still tend to go ahead, we may need to use a different foreshore
