The neighborhood is just west of the Federal Hill community and commercial district connected by West Hamburg Street, which is along South Charles and Light Streets, and the famous hill itself, which was the site of a celebratory picnic in 1788 after a parade of the various guilds, organizations and military units of old "Baltimore Town" to commemorate the ratification by Maryland of the new Federal Constitution, and later fortified with earthen embankments and large cannons of artillery by Northern troops of the Union Army a month after, during the Civil War to keep a close watch on and control on the Southern-sympathizing citizens of the City who had erupted in April 1861, in a riot attacking passing Massachusetts and Pennsylvania troops from the President Street Station on the east side from Philadelphia and the North, on their way to the nearby (a few blocks away with the Washington tracks running right by the Church) Camden Street Station of the famous Baltimore and Ohio Railroad to defend the National Capital of Washington from the newly seceded Virginians and Confederates.
