Visitor center…Amazing architecture, looks totally diff in zones of same boring buildings This castle is basically a welcome visitor center. Almost all the museums are free in DC and when I tried to find out why I got to know, it was James Smithson who was a British scientist who left his estate to the United States…

Rating: ⭐⭐⭐⭐⭐ Even with the main building currently closed for renovation, the Smithsonian Castle grounds are a must-visit in DC! We spent a wonderful afternoon exploring the Enid A. Haupt Garden and the surrounding architecture.

Smithsonian Castle with There is also a beautiful garden. . It is built of red sandstone and looks like a Medieval Revival style building. A small chapel like room and there is a historic carousel at the north entrance. Great Place to spend few hours for relaxing views in the heart of DC! Stunning architecture.
