Nationals Park is a baseball stadium along the Anacostia River in the Navy Yard neighborhood of Washington, D.C. It is the ballpark of Major League Baseball's Washington Nationals. Since its completion in 2008, it was the first LEED-certified green major professional sports stadium in the United States.
Designed by HOK Sport and Devrouax & Purnell Architects and Planners, the ballpark was initially expected to cost $670 million, with a later price tag of $693 million to build, financed almost entirely by D.C. This amount included $135 million in an upfront payment from taxpayer funds. The rest of the sum, about $535 million dollars, was funded by municipal bonds, putting the city deeply into debt. An additional $84.2 million was spent on transportation, art, and infrastructure upgrades, bringing the total cost to $783.9 million. The stadium has a capacity of 41,373. The Washington Monument and the Capitol building are visible from the upper decks on the first base side of the field.
