Green Monster - Citgo Sign

Citgo Sign

An electrically lit Citgo sign can be seen from inside Fenway, located outside the park, in the view above the left-field wall. The famous sign, located atop the building housing the Barnes and Noble Boston University bookstore on nearby Kenmore Square, was erected in 1965, replacing a "Cities Service" sign (Citgo's old name) that had been there previously. The sign is kept as a landmark. On October 15, 2008, a small fire caused minor damage to the sign.
