Even though it didn't open until 11:00 I went early knowing that because of its proximity to the Eiffel Tower, the metro and Trocadéro Square would be packed with visitors. Wandered around the gardens for a while (away from the hoards) then stopped at a nearby café.
I purchased, for an extra 3 euro the parcours visioguide - not the usual audio guide that is available in most museums. A device the size of a blackberry it gives audio explanation along with a slide show of extra information. A stark contrast to the visitors crowding Trocaadero Square I was virtually alone here. Maybe exagerating a bit - there may have been 6 other people.
The first floor houses the exhibits showing a chronological journey through France's architectural history between the 12th and 18th centuries. Some models, some actual size.
On the second level is the gallery of modern and contemporary architecture. Detailed displays show - through models, film, photographs, books and origianl documents - France's architectural develpment from 1851 through to present day. Two main sections focused on designing & building and architecture & society.
The upper level housed a history of wall paintings and stained glass. I wasn't allowed to use the flash on my camera so pictures of the two upper levels were very dark. Disappointing as the contemporary section was by far my favourite. My memory of this part will have to be my souvenir.
