The first thing I did in the first morning in Paris was to collect the 2-Day Paris Museum Pass that I had pre-ordered from Rue de Rivoli. This pass allows me access to over 60 museums in and around Paris. This is a very useful pass to have because it allow one to avoid the queue at the ticketing office. However, you have to remember that most museums in Paris is closed on Mondays.
My main stop for the day was the Louvre Museum. Continuously built over 500 years and previously a palace, the Louvre is one of the largest art gallery and museum in the world. The latest extension is the Louvre Pyramid built less than 20 years ago.
You have to be there to see for yourself the immense size of the Louvre — what you see below is just a part of the Louvre. There are more behind the back facade.
At the west end is the Arc de Triomphe du Carrousel which was built by Napolean. This is the start of the long wide avenue leading all the way to the Arch de Triomphe 9 km away.
The Louvre Pyramid is the main entrance to the Louvre. There were tight security checks the day I was there where most bags were checked.
