Interested in history? Interested in learning about not commonly known things about Washington, DC? Take a look at the new blog Architect of the Capital. Author Elliot Carter writes about the "interesting hidden side of Washington, DC."
Two of the posts: interesting federal government agency logos (Surprisingly Creative Branding From the Federal Government) and a tunnel which provided easy access to books for legislators and staff (Hidden Book Tunnel).
The blog is not affiliated with the Architect of the Capitol.
