The metropolis of London has been occupied for many centuries, and has acquired a number of subterranean landmarks.

These include:

• The Subterranean rivers of London
• The London Underground
• London deep-level shelters
• The London Post Office Railway
• Kingsway tramway subway
• Kingsway telephone exchange
• The Cabinet War Rooms
• The London sewerage system (designed by Joseph Bazalgette)
• Civil defence centres in London
• Tunnels underneath the River Thames
• Military citadels under London

London, like most other major cities, has extensive underground infrastructure for electricity distribution, natural gas supply, water supply, sewerage and telecommunications, including the BT copper local loops and optical fibre from numerous suppliers.
