I’m helping my husband, Michael Rothschild, re-arrange the window boxes in our bedroom upstairs. I do the lifting, not the nurturing; my thumbs are black. Two doors to the east scaffolders are erecting staging across our neighbour’s roof. Yet another loft conversion is in progress. The workmen are Polish.

Lady Diana Spencer, who would have turned 59 this summer, made a huge impact on British life. She helped modernise the monarchy, and her death in 1997 shocked the institution to its core.

Here we take a look around some of the sites in London with connections to the late princess.
