See the USS Constitution Fire its Cannons on July 4th!

I found out something new: Every July 4th, the USS Constitution sails from Boston Harbor out to Castle Island where it blows off its cannons. The army on shore responds with its own gunfire, and then the Constitution sails back from whence it came. Meanwhile, the crowds on shore and in private boats (and boat tours) watch with bated breath and cover their ears (it’s loud!) I had the privilege of seeing all this last week, and it just so happened I’d packed my camera, so I can’t wait to share the photos with you!

First, a few things about the USS Constitution. She’s the world’s oldest commissioned warship still afloat, built in 1797 to aid in protecting American ships from Barbary pirates.

In the War of 1812, cannonballs seemed to bounce off of her live-oak wood hull, earning her the name “Old Ironsides” as she captured five British warships over the course of the war.

The Navy considered scrapping her many times and finally retired her from active service in 1881 – the public couldn’t bear to see her torn apart, so she lives on as a museum ship at the Navy shipyard in Boston.

Most years, the USS Constitution is towed out to Castle Island with tugs, though sometimes she’ll come out under full sail.

The guns begin to go off at 11:30. Plenty of people arrive early and make a morning of it. I got a late start, so I was almost running down the causeway to get to Castle Island in time for the show. Thankfully, I ended up with five or so minutes to spare, so I missed the ship arriving, but I heard the cannons loud and clear!

I didn’t realize until I looked at the pictures later that I caught fire coming out of the cannon!

After the cannons on the USS Constitution go off (manned by the Navy), the Army takes over and shoots back using more modern cannons on the shore (the hill below Fort Independence). I didn’t realize this, so I didn’t turn around to see them or to take any pictures. I was pretty disappointed I didn’t see them, especially when others in my group said there were smoke rings. How fun would that have been to photograph!?!

Various pleasure crafts come out to see the cannons. They have a front-row seat, but they can also be in the way a little for photographs at times. Police boats patrol the area and ensure that no one gets too close to the cannons. There are also Navy vessels around for the fun.

Castle Island was once a true island some distance offshore. Land reclamation expanded Boston toward the island, and in 1921, the city connected it to the mainland via a causeway. The causeway is mostly taken up by the port (lots of shipping containers), but there is also a road and a nice sidewalk for walking.

Castle Island boasts a real fort, first built in 1634 (nicknamed “The Castle”) to protect the settlement on the mainland. iI was also a holdout for enemies of the crown prior to the American Revolution. The current fort (Fort Independence) was completed in 1851 and was mainly used during the American Civil War.

We walked around the fort to let the traffic subside a little after the show. The gate was open, but no tours were being offered yet, so we walked up to the rope blockade at the fort entrance and peeked into the parade ground. It was interesting, and while I’m sure you’d see more if you took the tour, it was enough for me.

We especially enjoyed seeing the historic Bobcat!

If you happen to be in the Boston area on July 4th, I highly recommend this experience! Though you might want to bring earplugs (I wish I’d brought mine!)

Practical Stuff for seeing the 4th of July at the USS Constitution

The guns go off at 11:30 sharp (check to make sure the timing is correct for the year you plan to visit). Arrive early to get a good view (so I say; I showed up with about 5 minutes to spare and stepped over someone’s lawn chair to get a front-row vantage point!)

Most people sit on the hillside behind the fort, and they get a great view. I went out on a small pier (approx. 42.33918950, -71.009799).

Vehicles can drive to a small (well, not that small unless you’re talking the kind of crowds that come to see the USS Constitution) parking area near the fort (approx. 42.3386193, -71.0141567); there is other parking in the area (both free and paid), but be careful to read the signs so you don’t end up in a “tag required” zone (usually only enforced between 6pm and 10am on weekdays).

There is no fee to enter Castle Island State Park or the fort.

There are restrooms on the parking area side of the fort.

Tours are offered through Fort Independence throughout the day. You can check the schedule online. The tours are free but donations are appreciated.

Walking out to Head Island would have been a ton of fun, but we opted to go back the way we came.

There are quire a few beaches in the area around Castle Island, mostly a favorite with the kids, though there were adults sitting in the shade or enjoying the shade.

4th of July is a busy time on Castle Island, but it’s not bad in terms of traffic in the rest of the city. The locals I was with kept saying, “I can’t believe how little traffic is out today. I’ve never seen so few cars on this road” as we drove around.
