The largest of London's lost rivers, the River Fleet flows four miles (6.4 kilometers) underground through downtown before it enters into the Thames. Here, it splits into two 12-foot-high (3.7-meter-high) brick tunnels not far from St. Paul's Cathedral.

A number of watercourses through London were buried over the centuries, including the River Westbourne, which flowed from Hampstead through Hyde Park to Sloane Square and into the River Thames at Chelsea.
