The Louvre Pyramid serves as the main entrance to the museum and also makes for a nice juxtaposition to the rest of the palatial building and grounds. It’s basically a glass and metal (steel?) pyramid sitting in the middle of the main courtyard to the complex. Unsurprisingly, there was quite a bit of controversy surrounding it when it was introduced. However, it has since become quite popular with the hordes of tourists that visit the museum each day. If you stand on one of the concrete blocks near the roundabout it’s easy to get of a photo of yourself touching the tip of the pyramid, similar to the one everyone takes when they go to the Taj Mahal.
