Washington Monument
At the turn of the 19th century Baltimorians lobbied for a monument dedicated to the United States' first president, and in 1829 Washington's first monument finished construction. It was designed by architect Robert Mills who later went on to design that other Washington Monument in D.C. It is now a focal point in the Mt. Vernon neighborhood.
The Walters Art Museum
An excellent museum donated to the city by father-and-son railroad tycoons William and Henry Walter, fervent collectors who purchased much of its massive and diverse collection as well as the buildings that host it. It is best known for its collection of 19th century European masterpieces. Be sure to enter or exit from its Charles Street entrance, where you'll pass through a magnificent indoor courtyard modeled after the Palazzo Baldi in Genoa.
Hackerman House
An elegant late-classical-era home built in 1850, it was donated to the city of Baltimore by its last owners, Willard and Lillian Hackerman, in 1984. The city renamed the house in their honor and took advantage of its location to expand the adjacent Walters Art Museum. It now hosts the Walters' collection of Asian Art, but is open only on the weekend, and can only be accessed from within the museum. From the front rooms on the third floors you can sneak a bird's-eye view of the monument plaza.
