This is one of the DC's Heritage Trails. Signs are posted along the trail (on the sidewalk) to point out places of historical interest. The trails provide great opportunities to learn local and national history, as well as visit DC's distinct neighborhoods.
This trail will appeal most to people who enjoy US government history. Architecture and city planning enthusiasts will probably find it interesting, as these elements are prominently discussed along the trail. To read more about what you will see on the trail, read our Federal Triangle Heritage Trail feature article.
Make sure you go into the Old Post Office and take the elevator up to the top for some of the best views of Washington DC. While many of the buildings you will see are not the most aesthetically spectacular, the details can be very interesting. Check out some of the pics below.
We highly recommend you download and print the trail booklet for the Federal Triangle Heritage Trail provided by Cultural Tourism DC. It contains all the text from the trail signs so you can do a little learning before you head downtown.
Note that you are close to, or pass several attractions along this trail. They include, but are not limited to, the National Aquarium, National Gallery of Art, National Museum of American History, National Museum of Natural History, the National Archives, and the Newseum. You can easily take an excursion from the trail to check out any of these museums. This is highly recommended during the summer, when it is really hot.
