Fenway

"Nothing defines Boston quite as much as the town’s devotion to sports (10 championships since the turn of the century doesn’t hurt), and with all due respect to the five-time-Super-Bowl-champion Patriots, it’s Fenway Park, not Gillette Stadium, that’s the temple of sports fandom. Opened in 1912, the quirky green bandbox between Lansdowne Street and Yawkey Way is almost as famous for its obstructed-view seats as it is for its fabled Green Monster wall in left field, but that’s a price Sox fans gladly pay in exchange for maintaining Fenway’s historic layout. It's both intimate and loud on game day even in years when the Sox aren’t contenders (tickets are often hard to come by, so plan ahead); the old ballpark also is open for one-hour, behind-the-scenes tours that take you inside and atop the Green Monster. You'll be able to stroll around the field (the warning track, not the grass), and visit the press box, the Pesky Pole, and (on days with no games) the dugouts and bull pens."
