George Washington didn't just sleep here. During the Revolutionary War, our future first president ordered the first…More raising of the American flag right atop this very hill. On January 1, 1776, the "Grand Union Flag" (as it was then called) was raised on a ship's mast standing tall on Prospect Hill. Some 4,000 Continental Army troops encamped on the hill celebrated with a gun salute and cheering. As those troops then fought during the siege of Boston, historians say the sight of the flag kept them going. And by March, they drove the British out.
Today, a replica of the flag still flies atop Prospect Hill Tower, which was built along with the park in 1903. You'll notice the flag is not the familiar Stars & Stripes. To better represent the new colonies, the first flag's British crosses were replaced with 13 stars in 1777. So consider the park your chance to see the American flag version 1.0.
You can also relax and take in sweeping views of Boston here. Climb the steps to the tower and the Boston skyline is yours. A stately park with shade trees, green lawns and benches surrounds the tower. Picnickers, sunbathers and dog owners enjoy the grounds. Residents gather each year on January 1 to commemorate the raising of first flag.
