BBC Mystery surrounds the appearance of hundreds of Victorian hobnailed shoes which have washed ashore on a beach.
The black leather boots, thought to date back to the 19th Century, were discovered by volunteers cleaning up rock pools on Ogmore By Sea Beach in the Vale of Glamorgan, south Wales.
Emma Lamport from the Beach Academy social enterprise which found the shoes said there was speculation locally that they could be from a shipwrecked Italian cargo vessel said to have struck nearby Tusker Rock about 150 years ago.
Author and mudlarker Lara Maiklem said the boots were “definitely Victorian” and likely to have come from a shipwreck due to the quantity found.
