The Palisades, or simply Palisades, is a neighborhood in Washington, D.C., along the Potomac River, running roughly from the edge of the Georgetown University campus (at Foxhall Road) to the D.C.-Maryland boundary (near Dalecarlia Treatment Plant). MacArthur Boulevard (once called Conduit Road) is the main thoroughfare that passes through the Palisades. In 1893, this subdivision was laid out by the Palisades Improvement Company. The Palisades had the Great Falls Electric Railway that ran from 36th and Prospect streets out to Glen Echo. The International Athletic Park and Amusement Company secured a large block of the Palisades and constructed a Bicycle Track and General Amusement Park, which opened on Decoration Day in 1896. Also encompassed within the Palisades is the neighborhood of Potomac Heights, which is bounded by Loughboro Road at the north end, Arizona Avenue at the south end and MacArthur Boulevard and the Potomac River. - source: Wikipedia
