In 1984, the Museum of London set up a Wall Walk from the Tower of London to the museum, using 23 tiled panels. A number of these have been destroyed in subsequent years. At Noble Street, the panels were replaced by etched glass panels. These were intended as a prototype for new panels along the entire walk, but no further replacements have been made. One of the largest and most readily accessed fragments of the wall stands just outside Tower Hill tube station, with a replica statue of the Emperor Trajan standing in front of it. There is a further surviving section preserved in the basement of the One America Square building. There are further remains in the basement of the Old Bailey.
