While the stadium was built in 1912, it was rebuilt in 1934. It is the oldest active ballpark in MLB. Because of its age and constrained location in Boston's dense Fenway–Kenmore neighborhood, the park has been renovated or expanded many times, resulting in quirky features including "The Triangle", Pesky's Pole, and the Green Monster in left field. It is the fifth-smallest among MLB ballparks by seating capacity, second-smallest by total capacity, and one of eight that cannot accommodate at least 40,000 spectators.

Fenway has hosted the World Series 11 times, with the Red Sox winning six of them and the Boston Braves winning one.[note 1] Besides baseball games, it has also been the site of many other sporting and cultural events including professional football games for the Boston Redskins, Boston Yanks, and the New England Patriots; concerts; soccer and hockey games (such as the 2010 NHL Winter Classic); and political and religious campaigns.

April 20, 2012, marked Fenway Park's centennial. On March 7 of that year, the park was added to the National Register of Historic Places. Former pitcher Bill Lee has called Fenway Park "a shrine". It is a pending Boston Landmark, which will regulate any further changes to the park. The ballpark is considered to be one of the most well-known sports venues in the world and a symbol of Boston.
