Gray on gray, Thames mist swirls down Water Lane (right), just inside the Tower's outer wall along the river. The Thames once lapped against the wall at rightand the round Lanthorn Tower which, tradition says, served as a lighthouse until Edward Ifilled in this area in the late 1200s. He also built the outer wall, which stands behind the beef eaters' pub and its un marked portals. In later years the Lant horn Tower housed prisoners, who may have passed the time creating intricate wall carvings. Such stones of sorrow line the walls of the Beauchamp Tower (above), where scores of carvings, some broughtfrom other parts of the Tower, are displayed.
