A beach in the heart of London

The River Thames is tidal where it flows through the heart of London. At low tide, sandy beaches appear alongside the river’s banks. What is often beneath the water is revealed for a few hours. People, known as ‘mudlarks. wander along the sandy beaches looking for objects and fragments that have been thrown into, or lost in, the water over the many centuries that the city has been in existence. I have never attempted mudlarking, but many people enjoy searching for lost treasures.
