When traveling what we often see is the outside of buildings. We walked by this impressive building several times, before we decided to go inside and see what it contained.
We were amazed at what we found inside.
An army museum is not something I would venture into normally, especially when there are so many art museums to visit in Paris. This museum was well worth going inside. For more information on the museum visit their web site at: http://www.invalides.org.
