Les Anneaux de Buren, Nantes, Loire-Atlantique (44)

From the mid-eighteenth to the nineteenth century, the number of French slave trading expeditions was 4220, and those from Nantes were the largest by a huge number: the figure 1714 far exceeds any other port, and in fact the next four largest concerned ports in total add to less than this number. Nantes has every right to be ashamed of its past, and these eighteen anneaux by Daniel Buren and Patrick Bouchain represent the slaves' rings in the ships' holds. At night they are coloured red, green and blue.

In addition, a street by the river has been named after the American feminist and abolitionist Lucy Stone.
