Thanks for the comments. I believe the glass pyramid was built sometime in the late 80s or early 90s - and you enter the Louvre via the pyramid down a spiral staircase. Sadly, tripods are out of bounds in such areas, especially the Louvre. The tripod police are usually out in full force! All these shots were handheld. If you're visiting Paris, definitely bring a monopod, and plenty of fast film!
