Skylight

Had a day in London with the grandsons, and having seen Nelson's column and the lions in Trafalgar square, we walked down Whitehall to see the changing of the Household Cavalry Guard before discovering an enormous queue for entrance to the Natural history Museum. Dived underground again to emerge at a less besieged British Museum where we saw Mummies, Roman Legionnaires' swords and helmets, and other wonderful things. The (not so) new roof over the centre courtyard was striking in the early afternoon sun.
