Which of these London landmarks is not a World Heritage Site?

The London Plan sets out policies to conserve and enhance London’s World Heritage Sites and their settings. It states that the Mayor will produce guidance on defining the settings of London’s World Heritage Sites.

There are four World Heritage Sites and one potential site on the Tentative List in London:

Palace of Westminster and Westminster Abbey, including St Margaret’s Church

Tower of London

Maritime Greenwich

Royal Botanic Gardens, Kew

Darwin Landscape Laboratory (Tentative List)

Each has been designated a World Heritage Site because they are deemed to be of Outstanding Universal Value (OUV) and acknowledged to be of international significance.

The sites themselves are set in a very dynamic, complex urban environment in which pressure for development is high. However one of the things that makes London distinctive is the way it combines old and new, protecting heritage but encouraging change.
