1865 was perhaps the most consequential year in presidential history, when, on the 14th of April, a prominent actor at Ford's Theatre and Confederate sympathizer John Wilkes Booth shot President Lincoln in his balcony seat. Attendants carried Lincoln across the street to a small bedroom in the small
rowhouse across the street, but the doctors were unable to save the president. He died early morning the next day. This isn't so much a museum—it's just a small room with a few plaques, recreated to look as it did on that day. The house is operated by the National Park Service, and visited via tours from Ford's Theatre.
