What Is Mudlarking? A Beginner’s Guide to River Treasure Hunting

Mudlarking may sound like a quirky pastime, but it’s a fascinating blend of history, adventure, and discovery. What started as a means of survival in 18th-century London has evolved into a popular hobby for those eager to explore riverbanks for relics of the past. Whether you’re drawn by curiosity, history, or the thrill of the find, mudlarking offers a unique way to connect with the stories hidden beneath the surface.

What Is Mudlarking and Where Did It Begin?

Mudlarking is the act of searching along riverbanks—especially tidal rivers like the Thames—for lost, discarded, or buried objects from the past. While today it’s considered a recreational activity, its roots lie in a much harsher reality.

A Brief History:

18th–19th Century London: The term “mudlark” originally referred to impoverished individuals, often children, who scavenged the Thames foreshore for anything they could sell—coal, nails, bones, bits of rope, and scrap metal.
A Dangerous Living: These early mudlarks worked in hazardous conditions, wading barefoot through raw sewage, broken glass, and industrial waste. The work was physically demanding and extremely unsanitary.
Decline of the Profession: With improvements in public health, sanitation, and poverty levels during the late 19th century, mudlarking as a job faded from view.
The Rise of Hobby Mudlarking: In the late 20th and early 21st centuries, mudlarking reemerged—this time as a historical hobby. People began exploring riverbanks for relics, such as old coins, pottery, and tools, connecting with the past through hands-on discovery.
Modern Mudlarking Today: Especially popular along the Thames, today’s mudlarkers often hold permits and adhere to archaeological best practices, sometimes contributing their finds to museums or historical records.

Key Takeaway: Mudlarking evolved from a desperate means of survival into a fascinating and educational hobby that offers everyday people the chance to uncover real pieces of history.

What Kind of Items Can You Find While Mudlarking?

Mudlarking offers the thrill of discovering forgotten objects from different historical periods. The items you find often tell fascinating stories about past lives and activities along the riverbanks. While some finds are common, others are rare and highly sought after.

Common Mudlarking Finds:

Coins and Tokens: Old coins from various eras—Roman, Medieval, Georgian, and Victorian—are some of the most exciting finds. They offer insights into trade, economy, and the people who lived in the area.
Pottery Shards and Ceramics: Pieces of ancient pottery, porcelain, and broken plates are frequent discoveries. They can range from simple utilitarian items to ornate, decorative pieces.
Clay Pipes: Fragments of clay smoking pipes are common, especially in areas around former taverns and docks. These items can date back to the 16th and 17th centuries.
Buttons and Military Badges: Old buttons, particularly from uniforms or civilian attire, provide a glimpse into the fashion and social status of past societies. Military badges and medals from different wars are also frequent finds.
Glass Bottles and Jars: While glass breaks easily, many glass bottles—especially those from the 19th and early 20th centuries—are still in excellent condition.
Jewelry and Personal Items: Occasionally, mudlarkers uncover pieces of jewelry, such as rings or brooches, as well as personal belongings like keys or pocket watches.

Rare and Valuable Finds:

Ancient Relics: In some areas, you might stumble upon prehistoric items like stone tools or Bronze Age artifacts.
Viking and Roman Artifacts: Every mudlarker dreams of discovering Roman coins, weapons, or Viking items, though these are rare and often require a trained eye to identify.
Skeletons and Bones: Occasionally, bones or even partial skeletons have been uncovered, which may require professional archaeological attention.

Key Takeaway: Mudlarking provides the opportunity to discover a diverse range of items, including common coins and pottery, as well as rare historical treasures, each with a unique connection to the past.

Do You Need a Permit to Go Mudlarking?

Mudlarking, while an exciting and historical hobby, is not without its regulations. In many places, particularly along the River Thames in London, a permit is required to ensure that the activity is done responsibly and legally. Understanding the rules and obtaining the proper permissions is essential for anyone serious about mudlarking.

The Importance of Permits:

Legal Requirements: In the UK, mudlarking on the River Thames requires a permit issued by the Port of London Authority (PLA). This is to ensure that mudlarkers don’t interfere with conservation efforts or disturb areas of significant archaeological importance.
Different Types of Permits: Thames mudlarking permits come in two primary varieties:
- General Mudlarking Permit: This permit allows individuals to search for artifacts on the foreshore, the exposed part of the riverbank at low tide.
- Licence for Digging: If you plan to use tools like spades or trowels to dig below the surface, you’ll need a digging permit. This is strictly regulated and requires additional documentation.
Where You Can and Can’t Go: Even with a permit, mud-larking is not permitted in restricted zones. These include areas near archaeological sites or regions designated for environmental protection. The PLA helps regulate these areas to preserve the integrity of the river and its history.
International Regulations: Mud-larking rules vary widely outside of the UK. For example, in the US, Canada, and Europe, some places also require permits to dig or collect items from historical sites or protected areas. Always check local laws before you head out.
Why Permits Matter: Permits ensure that mudlarking is done safely and responsibly, while also protecting important heritage sites. By requiring permits, authorities can track activity, enforce rules, and ensure the preservation of valuable historical artifacts.

How to Get a Permit:

Apply Online: In the UK, obtaining a mud-larking permit for the Thames is straightforward. Applications are usually submitted online via the Port of London Authority’s website, which also offers guidelines on when and where you are permitted to search.

Fees and Duration: Fees for permits vary, and the duration of the permit depends on the type of activity you wish to pursue. Generally, a permit is valid for a set period, such as a year, and needs to be renewed if you plan to continue mudlarking.

Key Takeaway: Before setting out on a mudlarking adventure, always ensure you have the necessary permit. This not only keeps you within the bounds of the law but also helps protect the rich history beneath the river’s surface.

The Ethics of Mudlarking: What to Keep, Report, or Leave Behind

Mudlarking is not only about finding treasures—it’s about responsibly preserving history. Ethical mudlarking ensures that the objects you discover are treated with respect, and it helps protect important archaeological sites.

What to Keep:

Personal Finds: Items that are not historically significant, such as modern coins, jewelry, or mundane objects, can usually be kept as souvenirs.
Non-Treasure Finds: Everyday items, such as clay pipe fragments, glass bottles, or buttons, that are not protected by law can be kept for personal collections.

What to Report:

Historical Artifacts: Items older than 300 years, or those made from precious metals, must be reported to the Portable Antiquities Scheme (PAS) in the UK.
Treasure Finds: According to the Treasure Act, you must report any gold or silver items, or anything that’s part of a larger archaeological find.

What to Leave Behind:

Protected Sites: Never disturb protected areas, such as those designated as archaeological sites or nature reserves.
Culturally Sensitive Finds: If you encounter items of cultural significance (e.g., human remains), please get in touch with local authorities or archaeologists for guidance.

Key Takeaway: Ethical mudlarking involves adhering to legal requirements, respecting historical artifacts, and leaving protected or culturally significant finds for experts to examine. Your actions help preserve the past for future generations.
