Baltimore's museum of the common man defies the idea that history is just about politicians, wars, and artists. You'll see recreations of a cannery, a turn of the century textile factory, a printing press, Dr Bunting's old pharmacy, and exhibits on the Domino Sugar Factory. There are plenty of good hands-on activities for kids—they can even become child laborers in the textile shop!
The Baltimore Museum of Industry is a museum in Baltimore, Maryland, United States. Located in an old cannery complex, the museum has exhibits on various types of manufacturing and industry from the early 20th century. There are several hands-on sections with working equipment and other artifacts.

This big hilly park is one of Baltimore's best points for picture taking, as it overlooks the Inner Harbor, with great views of both the north and south skylines. You'll note that the cannons all seem to be awkwardly pointed at the city's central business district. The cause for this was the Union troops's suspicion of the famously irascible and rebellious Baltimoreans from siding with the Confederates in the Civil War (or simply from generally rioting). They set up on this well located hill to intimidate the city into submission.
Baltimore Ravens
Baltimore's new football team, in the form of the former Cleveland Browns, is wildly popular with locals, especially following their Superbowl wins in 2000 and 2013. As for the stadium itself, known unimpressively as "M&T Bank Stadium," but better referred to "The Bank", "The Nest", "The Asylum," or just "Ravens Stadium," is new as of 1998 and quite nice. For food, be sure to pick up some boardwalk fries. For parking, just don't. It's $40 and game day traffic is emphatically not fun.
Baltimore Orioles
The local baseball team plays at Oriole Park, better known as Camden Yards. It's often considered one of the nicest in the nation, with a retro style, but modern facilities (constructed in 1992). No name is better associated with the stadium than Cal Ripken Jr., who set the world record for playing 2,131 consecutive games on 6 September 1995, (a little less well known, but still historic, was Eddie Murray's 500th home run, exactly one year later to the date). Avoid trying to park here, for the same reasons as below for Ravens Stadium. Even when a game is not being played, the team still offers tours of the ballpark starting in March (though check their website for times).

Really a must-visit for any tourist in Baltimore, this is the birthplace of the Star Spangled Banner, the United States National Anthem. The fort's military history is best known for its central role in the defense of the country in the War of 1812, simply named the Battle of Fort McHenry. At the time, Baltimore was the industrial powerhouse of the United States, and was a critical producer of ships and armaments. Fort McHenry remained relevant in future wars: a prison for captured Confederate soldiers in the Civil War, a military hospital during WWI, and again an active Coast Guard base during WWII. Since 1925 it has been designated as a National Park (and since 1939 doubly listed as a National Monument), and is today a museum, with plenty of cannons and nooks and crannies to explore. Back to the National Anthem, it was Francis Scott Key, who escaped here from British captivity in the War of 1812, and joins Edgar Allen Poe, Thurgood Marshall, and H L Mencken as a preeminent icon of the city and the eponym for dishes at restaurants, bridges, and one impressive golden statue in Bolton Hill. He might be a little sad to see that the flag is not still there. It was getting extra raggedy after all these years, and was moved to the National Museum of American History in Washington, D.C. for preservation.
