Old Ironsides
In this historic park is the warship U.S.S. Constitution which is vital to Boston's history. The U.S.S. Constitution now serves as a training ship and is still commissioned for battle, making it the oldest warship in the world. It's over 205 feet (62 m) tall and weighs 2200 tons.
Tour famous Old Ironsides, but first enjoy all-ages hands-on exhibits on sailing skills and crafts.
Boston Navy Yard
Another Historical landmark are the grounds of the Charlestown Navy Yard, which was established over 200 years ago. The navy yard is located in the Boston National Historical Park, and from here you can access a visitors center, museum, and of course the USS Constitution and the Cassin Young.
Also known as the Training Field, this was a common grazing area and militia parade ground during colonial times. The centerpiece of the park is the Soldiers Monument, built in 1872 and dedicated to the men of Charlestown that fought in the American Civil War.
City Square is one of the city's newer parks, although the history of parks on this site dates back to 1629 when Market Square was laid out and Charlestown was still a separate city. In 1901, an elevated railroad was built through the square and then the busy Tobin Bridge was constructed. The rail line was eventually torn down and the Tobin ramps were put into a tunnel in the 1990s, allowing the park to be reconstructed above the highway.
Built in 1943, this shady oasis was built by Harvard University as a memorial to its namesake founder. The park is a little worse for wear, but there is a restoration fundraising campaign in the works.
