Stepping into this stadium is like walking back in time. With its signature feature of the Green Monster, the 37-foot high left field wall, and a manually-operated score board, Fenway Park is a unique piece of civic history. The building opened in 1912 and is now America's oldest baseball park, home to the famed Red Sox. Although the structure has endured several fires over the years, it still stands strong. Opens daily at 9am.
