Fort McNair, Washington, D.C.

Grant Hall was built as an addition to a former penitentiary, and was constructed between 1830 and 1831. The penitentiary became the center of national attention in 1865 when the trial and sentencing of those implicated in the assassination of President Lincoln was held on the third floor of this building. Four conspirators were sentenced to death, including the first woman ever executed by federal order, Mary Surratt.
