Mudlarking, the hobby of searching the banks of London's River Thames for historical artifacts, has experienced a dramatic increase in popularity, with a waiting list of over 10,000 people for permits. This surge in interest, particularly amplified by social media during the COVID-19 pandemic, has transformed what was once a niche activity into a highly sought-after pastime. Social media influencers, like Claire Mudd and Laurence Paige, whose "@muddlarks" account garnered over 30,000 followers, played a significant role in bringing mudlarking into the mainstream, with one video of a Georgian ring receiving more than 1.9 million views.
The Port of London Authority (PLA), which grants permits for mudlarking, initially saw the number of permit holders double from 2019 to 2022, reaching over 5,000. Alarmed by this rapid growth, the PLA paused new applications in 2022 and conducted studies to determine a sustainable number of permit holders. In late 2024, they reinstated permits with a cap of 4,000 holders and introduced a waiting list, which quickly swelled to over 10,000 people and was subsequently closed.
The new regulations have created challenges for veteran mudlarks, some of whom fear they may lose their permits and struggle to re-obtain them. However, the PLA has offered a concession for accomplished mudlarks, allowing renewable permits for those with a significant record of finds and contributions to London's cultural life. Experts emphasize the value of experienced mudlarks, who contribute approximately 700 historically significant discoveries annually to the Portable Antiquities Scheme database. These finds are crucial for archaeological understanding, filling gaps where professional archaeologists lack resources.
