The Orioles’ baseball park, Camden Yards, occupies an entire city block west of the Inner Harbor. It was the first ‘retro’ ball park, which reconciled Major League Baseball’s need for more space with fans’ nostalgia. Painted baseballs on the sidewalk lead two blocks northwest to the birthplace of a baseball legend; it’s now the Babe Ruth Museum (410-727-1539; www.baberuthmuseum.com; 216 Emory St; adult/child $6/3; 10am-5pm), which pays homage to one of the sport’s all-time greats. It’s open to 7pm on Orioles’ game days.
