March 17th in Boston is loud. If you’ve ever been caught in the crush of Southie during the parade, you know exactly what I mean. But while the rest of the world thinks we’re just celebrating St. Patrick, locals know there’s a second, much quirkier reason for the holiday. It’s called Evacuation Day Boston MA, and honestly, it’s one of the most brilliant pieces of political maneuvering in American history.
It’s a holiday. It’s a traffic nightmare. It’s a historical middle finger to the British Empire.
Most people think the city shuts down because of the Irish. They aren’t totally wrong, but they aren't totally right either. Back in 1901, city officials realized that since everyone was already skipping work to celebrate St. Paddy, they might as well make it an official holiday. But they couldn't just name it after a saint in a strictly secular government. So, they looked at the calendar, saw that George Washington kicked the British out of Boston on March 17, 1776, and said, "Perfect. We'll call it Evacuation Day."
Smart, right?
What Really Happened on Dorchester Heights
To understand why this matters, you have to picture Boston in the winter of 1775. It was a mess. The British were hunkered down in the city, feeling pretty safe because they had the best navy in the world and Boston is basically a giant harbor. Washington was outside the city, frustrated and lacking the heavy hardware to do anything about it.
Then came Henry Knox.
Knox was a former bookseller who decided to haul 60 tons of cannons from Fort Ticonderoga in New York all the way to Boston. Through the snow. Over mountains. Using oxen. It sounds fake, like a tall tale you’d tell kids, but it actually happened. When those cannons arrived, Washington didn't just start shooting. He waited for a specific night in March.
On the night of March 4, 1776, the Continental Army pulled off a logistical miracle. They moved those massive cannons onto Dorchester Heights, which overlooked the city and the harbor. To keep the noise down, they wrapped the wagon wheels in straw. They built "gabions"—basically giant wicker baskets filled with dirt—to create instant fortifications because the ground was too frozen to dig trenches.
When the sun came up, British General William Howe looked up at the hills and supposedly said, "The rebels have done more in one night than my whole army would have done in a month." He wasn't exaggerating. The British fleet was now sitting ducks. They had two choices: try to storm the hill (which would have been a bloodbath like Bunker Hill) or leave.
The Great Exit
They chose to leave. It took a few days of tense negotiations and a timely storm that prevented a British counter-attack, but by March 17, the British navy was sailing out of Boston Harbor toward Halifax, Nova Scotia. They took about 1,100 Loyalists with them—people who lived in Boston but were still team-King George.
Boston was free. It was the first major strategic victory for the Continental Army in the Revolutionary War.
The South Boston Connection
If you go to South Boston today, you’ll see the Dorchester Heights Monument. It’s a tall white marble tower that marks the spot where those cannons sat. But if you’re visiting on March 17, you’re mostly going to see green. Everywhere.
There is a long-standing debate about whether Evacuation Day Boston MA is just a "ghost holiday" used to justify the St. Patrick's Day Parade. In a way, it is. For decades, the two celebrations have been fused together. The parade itself is technically the "South Boston St. Patrick's Day / Evacuation Day Parade."

You’ll see politicians riding in vintage cars, followed by colonial reenactors in tri-cornered hats, followed by bagpipers, followed by local unions. It’s a bizarre, wonderful collision of 18th-century military history and 20th-century immigrant pride.
Why the "Double Holiday" Matters
For the Irish immigrants who flooded into Boston in the 19th century, claiming March 17th as a legal holiday was a power move. At the time, they faced massive discrimination. By linking their heritage to a foundational American military victory, they made themselves "more American." They weren't just celebrating a Catholic saint; they were celebrating the day the American Revolution really gained its legs.
It’s essentially a masterclass in cultural integration.
Is Everything Actually Closed?
This is where it gets confusing for tourists and even some locals. Since it’s a Suffolk County holiday, it doesn't apply to the whole state of Massachusetts.
If you work in a state office in Boston, Chelsea, Revere, or Winthrop, you probably have the day off. If you work for a private tech company in the Seaport? You’re definitely at your desk. The post office stays open because they’re federal. Banks are usually open. But the municipal courts? Closed. The Registry of Deeds? Closed.
It creates this weird split-screen reality where half the city is grinding away and the other half is at a breakfast fundraiser in Southie listening to politicians tell jokes.
Modern Controversies
It hasn't all been parades and cannons. In recent years, there’s been a lot of talk about whether the holiday should even exist. Critics argue that it’s a "redundant" holiday that costs taxpayers money in lost productivity. In 2010, there was a serious push to eliminate it to save about $5 million in holiday pay.
It survived, mostly because of tradition. Bostonians are notoriously stubborn about their traditions. We like our weird holidays. We like Bunker Hill Day in June (which also only applies to Suffolk County). These days serve as a reminder that the Revolution didn't just happen in history books; it happened in our backyards.
Visiting the Sites: A Practical Itinerary
If you want to actually "see" the history of Evacuation Day Boston MA without just getting covered in green beer, you have to be intentional.
Dorchester Heights (Thomas Park)
Go here first. It’s the highest point in South Boston. The monument is beautiful, but the view is better. You can see exactly why the British panicked. You have a clear line of sight to the entire harbor. If you’re there on the actual anniversary, there’s usually a small ceremony with a color guard.
The Freedom Trail
While the trail covers the whole revolution, pay attention to the Old South Meeting House. This is where the tensions simmered before the evacuation.
Castle Island
Located at the tip of Southie, Fort Independence is a great spot to walk and think about the British ships sailing away. The current fort was built later, but the location was a key part of the city's defenses in 1776.
Little Known Facts About the Evacuation
- The Code Word: On the day of the evacuation, the password used by Washington’s troops to enter the city was "Boston," and the countersign was "St. Patrick." Washington knew exactly what he was doing by picking that date.
- The Looting: As the British left, they didn't go quietly. They smashed furniture, stole goods, and generally tried to ruin the homes of the patriots they were leaving behind.
- The First Parade: The first official Evacuation Day parade didn't happen until 1901, the same year the holiday was officially sanctioned.
- George Washington’s Visit: Washington didn't actually lead the troops into the city immediately. He was wary of smallpox outbreaks inside Boston and kept his main force back until he was sure it was safe.
Real Insights for Navigating the Day
If you’re planning to be in town for Evacuation Day Boston MA, you need a game plan.

1. Transportation is a nightmare.
Do not try to drive into South Boston. Just don't. The T (the subway) is your only friend, and even then, it’s going to be packed. Red Line to Broadway or Andrew is the standard move.
2. The "Breakfast" isn't for eating.
The St. Patrick’s Day / Evacuation Day Breakfast is a televised political roast. It’s where mayors, governors, and senators trade insults. If you’re a political junkie, it’s the best part of the day. If you’re looking for eggs and bacon, go to a diner.
3. Respect the neighborhood.
South Boston has changed a lot. It’s gone from a strictly working-class enclave to a high-priced real estate hub. But the pride in the 17th remains the same. If you’re visiting the Dorchester Heights monument, remember it’s in the middle of a residential neighborhood.
4. Check the calendar.
When March 17 falls on a Sunday, the holiday is often observed on Monday. This shifts the "day off" for government workers, so double-check if you have business at City Hall.
Why We Still Care
It's easy to dismiss this as a provincial quirk. But Evacuation Day Boston MA represents the moment the American experiment actually started to look like it might work. Before this, the "rebels" were just a ragtag group of guys who had lost at Bunker Hill and were freezing in the mud.
By forcing the most powerful military on earth to tuck tail and run, Washington proved that the Continental Army was a real force. It wasn't just a riot; it was a war. And it started here.

So, next time you see someone in Boston wearing "Kiss Me I'm Irish" buttons on March 17, remind them about the cannons. Remind them about Henry Knox and his oxen. Remind them that we’re also celebrating the day the British finally took the hint and left.
Actionable Steps for History Buffs
- Read "1776" by David McCullough. He spends a huge chunk of the book detailing the Siege of Boston and the Knox expedition. It reads like a thriller.
- Visit the Massachusetts Historical Society. They often have original documents and diaries from the people who lived through the siege.
- Walk the Heights at sunset. It’s the best way to get a sense of the geography that changed the course of the war.
- Check the official City of Boston website in early March for the specific parade route and street closure list, as it changes slightly every year depending on construction in the Seaport.
