Wellington Rocks are found on Tunbridge Wells Common, they are an outcrop of Tunbridge Wells Sandstone.
Named after the Wellington Hotel. In earlier times they were variously described as the High Rocks on Mount Ephraim, or as Castle Rock (either named after the nearby Castle Tavern, or because of the shape of rocks’ highest point). Early nineteenth century guides report that “small transparent pebbles are found on the paths of the Common, especially after rain. These crystals are called Tunbridge Wells Diamonds, and, cut and polished, form brilliant additions to the jewel-case”. Small rounded pebbles can still be seen here today embedded in the sandstone, and it is presumably the most attractive of these, eroded out of the rock, which were once collected.
