This is the most eastern building on the pier, it is a brick and terra cotta building with two prominent towers known as the Navy Pier Headhouse. The name was derived from the area, which at the time was known as the Headlands. Each tower housed a huge 2-million liter tank for the fire sprinkler system. The Headhouse is now home to Chicago's children museum. At the western side of the building is the recent 19 acre Gateway Park.
