These gardens are actually a roof garden with 3 art galleries underneath. This area used to be where they kept exotic and endangered animals before they opened the zoo.
There is an exhibit of large scale bronze bird statues called The Lost Bird Project depicting birds that are now extinct. This one shows a Heath Hen.
We explored the rather unusual "relics" in the Smithsonian Castle before crossing The National Mall to the American History Museum. The National Mall has at present a Folklife Festival featuring various countries.
The large Bamboo Installation or Flower Plaque looks very splendid with the Washington Monument as a backdrop.
