World Heritage Site

The Palace of Westminster and Westminster Abbey, including St Margaret’s Church was inscribed as a cultural World Heritage Site in 1987. 

The inclusion of this group of buildings on the world heritage list makes them one of 1092 sites worldwide considered to have ‘Outstanding Universal Value’ as part of the world’s cultural and natural heritage. The ‘Statement of Outstanding Universal Value’, sets out the qualities and characteristics of the site which make it internationally important.

The boundaries of the site are shown on the World Heritage Site map

Detailed information on management of the site can be found in the World Heritage Site Management Plan (PDF, 6MB) . This was adopted in 2007 and is currently being updated.  The conservation area audit for Westminster Abbey and Parliament Square Conservation Area also contains information on the site, its history and wider context. 

If you intend to submit an application for development which may affect the Outstanding Universal Value of the Site, this will normally need to be accompanied by a Heritage Statement which follows the ICOMOS HIA Guidance. The World Heritage Centre may also need to be notified. To ensure all the relevant stakeholders are involved, we recommend you seek pre-application advice.
