Former Police Box (Lamp)

The Former Police Box (Lamp) is a small historic site set into a lamppost at the southeast corner of Trafalgar Square in London. It was installed in 1826 and used a lamp that could be switched on from a control police station to signal nearby police officers. It is known as the smallest police station in London, but it was not an actual police station. There is no explanatory plaque or sign at the site.
