Extract from LVMF: Linear View: Westminster Pier to St Paul’s Cathedral 8A.1

Foreground and Middle Ground
169 The clear view of the Cathedral should not be obscured by tree growth in either the foreground or middle ground.

170 A Landmark Viewing Corridor will maintain the existing visual frame around the Cathedral created by the middle-ground buildings.

Background
171 The dome and peristyle of St Paul’s Cathedral should remain with a clear sky backdrop.
