When the Yankees moved into the new Yankee Stadium after the 2008 season, the Yankees established a new Monument Park behind the fence in straightaway center field, below the Center Field Sports Bar that serves as the batter's eye. Built of pearl blue granite from Finland, this new monument park features the five Yankee monuments in a central area around a black marble Yankees logo. This is flanked by two short stone walls which hold the retired numbers. The plaques are mounted on the back wall and the September 11 monument is on one end of the park.
