<P> The Morse Code that appears from top to bottom in the white lines of the American League scoreboard are the initials of former owners Thomas A. Yawkey and Jean R. Yawkey . </P> <P> Fenway's left - field distortion is offset by the odd shape and generous size of right field, which is 302 feet (92 m) (although its actual distance has been disputed over the years) along the line (almost the same as in left), but 380 feet (120 m) at its deepest . The bullpen was added along the right field wall in 1940 to shorten the distance for left - handed slugger Ted Williams' home runs to clear the fence . For years afterward, the bullpens were known as "Williamsburg". </P> <P> In 1936, the Red Sox installed a 23 - foot (7.0 m) net above the Monster in order to protect the storefronts on adjoining Lansdowne Street from home run balls . The net remained until the 2002--03 offseason, when the team's new ownership constructed a new seating section atop the wall to accommodate 274 fans . Wildly popular, these "Monster seats" were part of a larger expansion plan for Fenway Park seating . The Red Sox later added a smaller seating section in 2005, dubbed the "Nation's Nest," located between the main seating section and the center field scoreboard . </P> <P> Comprising yet another quirk, a ladder is attached to the Green Monster, extending from near the upper - left portion of the scoreboard, 13 feet (4.0 m) above ground, to the top of the wall . Previously, members of the grounds crew would use the ladder to retrieve home run balls from the netting hung above the wall . After the net was removed for the addition of the Monster seats, the ladder ceased to have any real function, yet it still remains in place as a historic relic . </P>

When were seats added to the green monster
