The National Archives Museum, Washington DC

This museum houses three important founding documents - the Declaration of Independence, Constitution, and Bill of Rights. Not copies, but the original documents, preserved from wear and tear using some really neat archiving technology. This alone makes it worth a visit. The museum also has exhibitions showcasing a sampling of the records that the National Archives (NARA) safekeeps. It's fascinating to learn about the volume and breadth of the records - from census data to maps to early photos and videos - and the process of acquiring, cataloging, and preserving them. They also talk about what makes a record worth preserving. Don't miss out on the fascinating video by the exhibition entrance that shows the journey the three founding documents took on their way to the Archives, and the technology employed to preserve them. Our visit lasted a little more than an hour. Prepare for lines and a security check to get in. Photos are strictly prohibited. The museum store is pretty standard and the cafeteria was closed during our visit. Admission is free.

In terms of the displays and information shared this is one of the best done of all the museum options in DC. The display of the 3 founding documents elicits goosebumps (no picture taking allowed anywhere inside) and several other really great displays demonstrating the width and breadth of information the National Archives maintains, preserves, and restores. If you're into history at all, this is a must visit. Check the website about peak times and reserved visits. We visited on President's Day weekend and were there at open on Sunday and walked right in.
