7 Unexpected Things You Might Find In The Thames

Kirsten Downer from Thames21 looks at the unusual things you might find in the Thames.

You can’t work at Thames21 without getting to know our great river, as well as its tributaries. You notice how the Thames makes an auditory ‘tinkle’, unlike other rivers, thanks to the amount of historical detritus it harbours. You get to know which banks can support a clean-up, and which are so silty that you’ll sink knee-deep; or precisely how long it takes for the wake-wave created by a passing Thames Clipper to reach you.

But you still come across surprise items, and that’s one of the reasons that we love our work. Sometimes we get to keep our finds; other times they get handed over to archaeologists, or the police. People have always thrown their waste in the Thames, and on our clean-ups you find rubbish that cuts across time. Common themes emerge: pleasure, pain, hope, vanity and violence.

1. Weapons

Unusual items found in the Thames, like this Anglo Saxon spearhead

The oldest weapon we’ve found was on the Chelsea foreshore in 2010. According to my colleague Ben, it was just sitting on top of the gravel when he noticed it. He says, "Someone told me it looked like a piece of an old gate and starting hitting it against the concrete wall to remove some rust". Thankfully, Ben rescued the item and sent a photo to the Museum of London, who identified it as an Anglo-Saxon spearhead from the 9th century – identifiable from the pagan period by its split socket.

Here’s a more recent weapon found, described by colleague Chris Coode as the "nastiest thing" he’s ever found in the river. It’s been painstakingly made by hand, for only one purpose.

2. Teeth

Unexpected objects found in the Thames: cow's teeth

Teeth last a long time, and can tell you much about their owner's life. The deep root and ground-down ridges of the gnashers above tell us this belonged to an animal which grinds its food. It’s most likely from a cow kept in one of London’s many slaughterhouses – I have no idea how old it is.

Human teeth are certainly one of the more unusual items you might find washed up on the Thames shore

But when you pick something like this up, there's no doubt you’re up close and personal with a former Londoner.

3. Message in a bottle

Stroll the Thames and you might find some unusual items washed up, like this message in a bottle

This message bottle came with a yellow rubber duck; duck races are still popular on the river. But not all message bottles are celebratory. "It might not be the happy thing you expect", says Chris.  "I’ve found a few over the years that are very bleak. People have powered all their pain into a message, and on some level are wanting the river to take their pain away."

4.  Spiritual offerings

Religious objects are sometimes found in the River Thames - should one remove them?

Many Thames shore finds point to an unbroken spiritual connection with the river. Modern and ancient Londoners relate to the Thames as a place for their hopes and dreams, as well as to commemorate the dead. It leaves you with a quandary, however; should you take these items out of the river, or leave them there?

This copper sheet contains Sanskrit writing and seems to be some kind of prayer slate, which would probably have been placed in the river along with funeral ashes.

5. Whistling lollipops and weird plastic

Whistling lollipops and other unusual finds in the River Thames

At a certain point on a Thames River Watch litter survey, we found a stash of plastic tubes with a small hole, which intrigued us. We finally realised that they were from Whistle Pops, a popular lollipop launched in 1979, which could whistle.

Plastic, of course, can often be found littering the Thames in London

We’re working to raise awareness of the worrying amount of plastic in the river. Identifying the plastic helps us work out where it comes from – we’re still wondering which objects these plastic items above were once part of. Please get in touch with our Thames River Watch project if you know!

6. 400-year-old clay pipes

Clay pipes aren't the most unusual find in the River Thames, but they are often older than you think

Clay pipes are common finds on the river, but some are older than you might think. Ones with small bowls are older, as tobacco was expensive. Complete clay pipe stems are a rarer find – pipes were rented out and got increasingly shorter with use. People snapped bits off as the stem got blocked with tar.

Holding a clay pipe stem, found in the Thames, between your fingers is a strange experience

Holding the stem between your fingers is a strange experience, knowing that someone else’s fingers held it, hundreds of years ago.

7. Equanimity

Magic happens when you step off the pavement and onto the foreshore. You get a new perspective, both literally and emotionally (as well as noticing more nature-based sounds and smells). Seeking out trash and treasure can get addictive. One of our volunteers says that she loves being by the river so much that she runs her social calendar by the tide timetables: "I love the opportunity to be by the river as much as I can" she says, "it’s like stepping outside time."

Important finds, such as worked pottery, jewellery, coins or other crafted items should always be reported to the Museum of London’s Finds Liaison Officer.
