2. Arc de Triomphe du Carrousel
Directly in the courtyard of the Louvre is the Arc de Triomphe du Carrousel that was commissioned by Napoleon to commemorate his military victories (along with the “other” Arc de Triomphe on the Champs Elysées).
Initially, on top of the Arc de Triomphe du Carrousel were placed the Horses of Saint Mark. They had adorned the Basilica of San Marco in Venice since the sack of Constantinople in 1204 and had been brought to Paris where they were placed atop Napoleon’s Arc de Triomphe du Carrousel.
After Napoleon Bonaparte’s defeat at the Battle of Waterloo, many of the countries he had previously conquered asked for their artwork back. The Horses of Saint Mark were returned to Italy and today there is a copy on top instead.
