Moving west along the waterfront from the aquarium, the USS Constellation, docked near Baltimore's World Trade Center, was the last all-sail warship built by the U.S. Navy. Commissioned in 1855, the ship saw action in the Civil War. It sailed into the Inner Harbor in the 1950s and is now open for tours all year round.
Towering over the ship, the world's tallest pentagon-shaped building offers a fantastic 360-degree view of Baltimore. The 27th floor of Baltimore's World Trade is an observatory.
