Baltimore Civil War Museum
Located near the President Street Station, it is the site of the first bloodshed of the Civil War when southern sympathizers clashed with Massachusetts volunteers transiting to Washington. The station, built-in 1849 and the oldest surviving railroad station in an urban setting, along with the Philadelphia, Wilmington & Baltimore Railroad were key parts of the Underground Railroad, a network of secret routes used by slaves to escape to freedom in the northern states and Canada.
