The Louvre hasn't changed much over the years. Yes a pyramid was added years ago and the old palace has been cleaned and restored over the years but pretty much the same inside.
However, the crowds are massive. Best to go early or late. Mid-day swells to unpleasant proportions.
So we trek through on an abbreviated five hour visit.
Alan's favorite Vermeers.
Your guess is a good as mine.
All in all, a pleasant visit to the Louvre. Especially since it was damp and cold outside most of the day.
