London submerged

I stumbled across these at the Museum of London -- an exhibition of very clever photomontages, mounted on light-boxes, showing London landmarks after major climate change or catastrophes or social upheaval:

From a submerged Palace of Westminster to a sand-bound Tower Bridge:

A shanty-town in Trafalgar Square:

To Horse Guards in a desert landscape:

Paddy-fields in Parliament Square:

To the final catastrophe, a shanty town built on London's royal parks:

Somehow in the middle of such poverty, the queen still manages to cling on to her private gardens at Buck House. Some things never change.
