On Saturday, September 19, the doors of three artist buildings across the South End open to the public at 11 a.m. and stay open until 5 p.m. both days. This is the 39th year the United South End Artists have run this weekend, and it is a genuinely old institution, older than most of the condos it now shares a zip code with. Ask a longtime resident what's happening this weekend, though, and there's a decent chance they'll answer with one word: SoWa. That answer is wrong, or at least incomplete, and understanding why is the difference between wandering the neighborhood confused and actually walking a planned loop.
South End Open Studios and the SoWa Open Market are not the same event. They were not founded by the same people, they do not share an office, and they exist for different reasons. One is a nonprofit artist collective that has been opening working studios to the public since 1986. The other is a for-profit vendor market that launched in 2003 and now runs every single Sunday from May through mid-November. They happen to occupy overlapping streets this particular weekend, which is exactly why the confusion persists, and exactly why it's worth untangling before you head out the door.
Two Organizations, Not One Festival
United South End Artists has run Open Studios since 1986, which makes this year's edition the 39th annual. It is free, it happens once a year on a fixed September weekend, and it exists to let the public into working studios that are otherwise private year round. Three buildings anchor it this year: the BCA Artist Studio Building at 551 Tremont Street, 46 Waltham Street, and 35-59 Wareham Street. These are not galleries built for foot traffic. They're the actual studios, meaning you're walking through the same space where the work gets made, not a curated storefront version of it.
SoWa Open Market is a different animal entirely. It's in its 23rd season this year, running every Sunday from May 3 through November 15 at 500 Harrison Avenue and Thayer Street, with more than 250 vendors rotating through over the course of the season. It's commercial by design, built around artisan goods, food trucks, and farm stands, and it draws crowds every single week regardless of what else is happening in the neighborhood.
So when Open Studios weekend lands on a Saturday and Sunday, as it does this year, you get one day where only the artist buildings are open and one day where SoWa is also running its regular weekly market a few blocks over. That's not a special crossover event. It's just what the calendar looks like when a fixed September weekend meets a market that runs every Sunday for seven months. Most visitors never clock this. Locals who've lived through a few Septembers usually do, which is why they treat the weekend as one continuous loop instead of two competing plans.
Where to Actually Go
If you're planning the weekend around both, here's what's real and where it is:
- BCA Artist Studio Building, 551 Tremont Street — one of the three core Open Studios locations, part of the Boston Center for the Arts campus
- 46 Waltham Street — a working studio building, open both days of Open Studios weekend
- 35-59 Wareham Street — the third of the three core buildings
- Piano Craft Gallery, 793 Tremont Street — not a studio building itself, but the site of a preview show ahead of the main weekend
- SoWa Open Market, 500 Harrison Avenue and Thayer Street — the weekly Sunday market, running through November 15 this season
Piano Craft Gallery deserves a separate mention because it functions as the unofficial preview. Ahead of the main Open Studios weekend, the gallery hosts a group show featuring more than 40 South End artists representing nine different artist buildings, giving visitors a chance to see a cross-section of the work before deciding which studios to prioritize once the doors actually open. The show stays up through October 4, so even if you miss the weekend crowds entirely, there's a window afterward to catch a curated sample of what was on view.
Why Sunday Is the Day That Matters
Saturday, September 19 is Open Studios only. You can walk all three buildings, talk to working artists, and never cross paths with a food truck. Sunday, September 20 is different. That's the day Open Studios overlaps with a live SoWa Sunday, which means the same afternoon that gives you access to working studios also gives you the market's usual lineup of vendors and food trucks a short walk away on Harrison Avenue.
If you only have one day, Sunday is the more efficient one, simply because it's the only day both things are actually happening. If you want the studios without the market crowd, Saturday is the quieter option. Neither choice is wrong. It just depends on whether you'd rather have the neighborhood to yourself or see it at full volume.
Between Stops
The walk between the studio buildings and the SoWa footprint runs past some of the South End's most consistent restaurant patios, which makes the weekend easy to build a full day around rather than a single stop. MIDA sits right at the corner of Tremont Street and Mass Ave, close enough to the Wareham Street studios that it's an easy detour rather than a special trip. Metropolis Café keeps a patio strung with lights along Tremont Street that's become a fixture for the neighborhood's weekend brunch crowd regardless of what else is on the calendar. A few blocks over on East Berkeley Street, Aquitaine keeps its full street-side patio open for the same kind of foot traffic, and Bar Mezzana's sidewalk seating at Ink Block works the same way if you'd rather end the day closer to Harrison Avenue.
None of this requires planning around reservations. It's more that if you're already walking the South End for the studios, these are the places that will already have their doors and patios open when you need a break.
What This Actually Means If You Live Here
The practical takeaway isn't complicated. Open Studios and SoWa are two different institutions with two different histories, and the only reason this weekend feels like one big event is that a fixed September date happens to land on a Sunday that SoWa was already going to run anyway. That's true most years, not just this one, which is worth knowing if you've always assumed the two were connected.
What is specific to this year is the Piano Craft Gallery preview running through October 4, which gives you a second chance to see the work even after the studios close their doors for the season. If you're new to the neighborhood, or if you've lived here long enough to have stopped paying attention, this is the weekend to actually walk it. Thirty-nine years is long enough that the event isn't going anywhere, but the specific mix of artists, buildings, and overlapping market days is different every September.
If you're already searching for what's happening in the South End this weekend, chances are you already know this neighborhood well enough to plan your own route through it. That instinct, paying attention to what's actually on your own streets, is the same one that matters when the time eventually comes to buy, sell, or simply understand what a specific block is worth. If that day arrives, Nikki Palladino has spent years watching how neighborhoods like the South End actually move, block by block, season by season. Let's Connect.
