If you're visiting New York City around the Fourth of July (or want to go armchair traveling), and you're interested in American history, this is the post for you. These sites are either connected to the American Revolution or show something of NYC's colonial period.
This list is limited to sites I have visited (so you won't see a photo from the
Prison Ship Martyrs Monument in Fort Greene, for instance). For each site, I also mention other neighborhood attractions. Enjoy!
The Bronx
Stockbridge Indian Memorial (Van Cortlandt Park)

You'll find this memorial in the northeast part of Van Cortlandt Park. It's a tribute to a group of Native Americans, allied with the colonists, who died in August 1778 in a clash with an overwhelmingly larger number of British and Hessian troops. (Here's an
article that goes into greater depth about the Stockbridge-Mohican community.)
In the neighborhood: Van Cortlandt Park is massive (one of the city's largest parks) and has golf courses, sports fields, and miles of
hiking trails. The
Van Cortlandt House Museum on the west side of the park dates from the 18th century, and during the Revolutionary War, both Washington and General William Howe, the commander of the British troops, made use of it. If you're in the area, you can also visit Woodlawn Cemetery, where a
variety of historic figures are buried. The cemetery is close to the east side of the park.
