The Enigmatic London Stone: Centuries-Old Limestone or Bath Stone?

In the heart of London's bustling financial district, near Cannon Street Station, lies the captivating London Stone, a mysterious piece of oolitic limestone encased in a recessed display at 111 Cannon Street (EC4N 5AR). The name 'London Stone' appeared around the year 1100, but its original placement and purpose remain elusive. The surviving portion, traditionally believed to be Clipsham limestone, has recently been questioned, with Bath stone also being proposed as a possible material.
