We were walking along the Rue Caulaincourt bridge over the south end of the cemetery when we spotted this pretty planting arrangement in yellow below.
Cimetière de Montmartre is the third largest of four necropolises built in the early 19th century, just outside the Paris city boundaries.
It was placed below street level, in an abandoned gypsum quarry, which had previously received the hundreds of bodies of those killed in the riots of the French Revolution.
The entrance is at the end of Rue Rachel, under Rue Caulaincourt.
