On March 17, 1911, the wooden stands at Boundary Field - home of the original Washington Nationals baseball team - burned to the ground.
The stadium occupied land in Northwest Washington bordered by Georgia Avenue, 5th Street, W Street and Florida Avenue, according to Wikipedia.
It was rebuilt and later renamed, Griffith Stadium, home of baseball's Washington Senators and football's Washington Redskins.
The Washington Post said the fire was started by a plumber's blow lamp and spread to an adjacent lumber yard.
