Westminster’s archaeological heritage provides important evidence of the City’s past. Investigation has revealed evidence of prehistoric, Roman, Saxon medieval and post medieval archaeology.

There may be much more which is yet undisturbed.

There are three Scheduled Ancient Monuments in Westminster protected under the Ancient Monuments and Archaeological Areas Act 1979.

These are:

  • Chapter House and Pyx Chamber next to the Cloisters, Westminster Abbey
  • the Jewel Tower
  • the subterranean commercial ice well, at Park Crescent West, W1

Westminster also has a number of Areas of Archaeological Priority where there is known archaeological interest or may be potential for new discoveries. These have recently been reviewed by the Greater London Archaeological Advisory Service (GLASS). Details of the extended areas they have identified which have archaeological potential in Westminster can be found on the Historic England website. These will also be included within our revised City Plan when it is adopted. Find out more about obtaining advice from GLASS and when we consult them.

When developing in these areas, you should seek professional archaeological advice. Any archaeological evaluation and investigation should be undertaken by an IFA registered Archaeological Organisation or a suitably qualified archaeological organisation.

Our validation requirements set out when an Archaeological Assessment may be required with your planning application.
