Former Land Uses Terrestrial Biome Bartholdi Park, a triangular parcel of land originally known Temperate broadleaf and mixed forests. as square 578 was initially developed, although minimally, around 1857. Through 1865 only one structure was in place on this parcel. By the 1890s there were a number of houses and a school on this property. By 1902 the Senate Budget Parks Commission, the McMillian Commission was, among other things, proposing the removal of buildings and Bartholdi Park public realm improvements (hard and soft infrastructure from what would become the National Mall. costs): $3,824,570 total. This included eventually moving the US Botanic Garden to it’s current location, including the Fountain to what became, Bartholdi Park. The cast iron fountain sculpted by Frédéric Auguste Bartholdi (later famous for the Statue of Liberty) previously stood at the 1876 Centennial Exhibition in Philadelphia’s Fairmount Park. Landscape architect Frederick Law Olmsted, Sr., who was redesigning the Capitol grounds at the time, learned that the fountain was available and recommended to Architect of the Capitol Edward Clark that it be bought and placed in a suitable location. The fountain in the parks center was purchased in 1877 by the United States Congress for $6,000 and placed at the United States Botanic Garden’s original site. A new water basin was built opposite the original U.S. Botanic Garden Conservatory’s north front to receive the fountain. Prior to 1930 construction of the new USBG off the mall, both parcels, 576 and 578 were cleared of existing development. At some point after 1865 the Washington Canal on the west border of square 578 was covered and became Canal Street (Washington Avenue). Square 578, future Bartholdi Park, was developed in the late 1800s with a number of houses along Canal St, First Street, SW, B Street SW (Independence Ave) and a school on First St. The fountain then moved to its present location in Bartholdi Park (square 578) in 1932 when the U.S. Botanic Garden was moved.
