Searching for history along the Thames

Sandy has been mudlarking for a hobby for the last five years, scouring the river banks for historical artefacts. Some of his finds are so rare they are displayed in museums.

"Over 2,000 years of time, everything has been thrown into the Thames, accidentally lost ... dropped so 2,000 years of history are down there," he said.

"It's really the thrill of almost like time travelling and knowing that the last person to touch this was from that time period," he added, describing the feeling of making a find.

Sandy, originally from Chicago, has found numerous artefacts like a Tudor comb, Victorian toothbrush and a Roman women's hair pin, which the Museum of London dated to AD 43.

"If you're in a field you could be out all day long, with the river you're restricted to about two or three hours," mudlark Nick Stevens said. "Unlike fishing where there's one of 10 fish that you're likely to catch, with mudlarking there is an infinite amount of variety in terms of what you could find."

While many just use the naked eye for their searches, others rely on metal detectors for which a permit from the Port of London Authority is needed. Digging also requires consent.

The select Society of Thames Mudlarks counts just a few dozen members, who have the necessary licences and can access restricted areas along the river.

Collaborating with the Museum of London, the mudlarks record their finds with the Portable Antiquities Scheme. Any item over 300 years old must be recorded.

"It's quite exciting to go down to a part of London that is only accessible for a very short amount of time," Sandy said.

"Thousands of years of London's history is still waiting to be discovered there on the Thames foreshore."
