Reference

The search did not provide specific names for the octagonal gardens at the Cour Napoléon, which are a part of the Louvre complex. It's worth noting that the Cour Napoléon now prominently features the Louvre Pyramid, but the historical or traditional names of these gardens aren't explicitly documented in the search results I accessed.

For more detailed or specific information regarding the nomenclature of garden areas within the Louvre, you might explore resources or historical archives related to Parisian architecture or the Louvre itself.

If you are visiting the area or interested in historical designations, onsite information and detailed guides at the Louvre Museum could also provide further insights.
