Across the street from the house where Lincoln died is the theater where he was shot. I guess that most people assume that he also died in Ford's Theatre, but that is not the case. Anyhow, here it is. I think that's the original theater above, and there is a newer entrance, shown below. It definitely looks a little too modern to be original.
PS-For those of you that don't know, the play Abraham Lincoln was watching when he was assassinated was Our American Cousin.
