In 2003, the Virginia Baseball Stadium Authority proposed five Northern Virginia sites as possible locations to host the relocating Montreal Expos. Pentagon Centre, shopping mall, was one of three sites in Arlington County. The other two proposed Arlington sites were a plot of undeveloped land closer to the Pentagon and a site in the neighborhood of Rosslyn. The issue was highly divisive and some Pentagon City residents launched a visible campaign against it. After the Arlington County Board opposed a stadium in Arlington, the final Virginia bid featured a site near Dulles Airport instead. Major League Baseball finally announced in the fall of 2004 that the Expos would move to the District of Columbia as the Washington Nationals.
