In the 2nd century, London (then called Londinium) was controlled by the Roman invaders, and a wall was built to protect it. Today sections of this city wall are still visible, mingling among the office blocks. Cross sections of parts of the wall show where medieval Londoners continued to maintain and add to the wall.
Areas of London still bear the names of the gates in the wall, the main ones being Aldgate, Cripplegate, Bishopsgate, Newgate and Ludgate.
Large sections of the wall can be seen close to the Museum of London and near Tower Hill station next to the Tower of London. A sign posted walk runs along the path of the wall between these two locations.
