If you've driven past 106 Route 13 more than a handful of times, you already have a mental picture of Andres Institute of Art: the old ski lodge turned welcome center, the brown sign, maybe a stray sculpture catching your eye through the trees. Most weeks, that's the whole story. A quiet 140 acres of woods with metal and stone scattered through it, free to walk, dawn to dusk, no reason to stop unless you're already stopping.
This month isn't most weeks.
Starting September 12 and running through October 4, the hill above that welcome center turns into an active studio. Sculptors invited from around the world will be on site, carving granite and welding steel in the open air, building the next pieces that join the park's permanent collection. This is the 26th year Brookline has hosted this exact ritual, and most residents who drive Route 13 twice a day have no idea it happens every single fall.
The Park You Know Isn't Finished. It Never Is.
The collection at Andres Institute isn't a fixed set of pieces someone installed once and left alone. It grows every year, on purpose, through something called the Bridges and Connections International Sculpture Symposium. Visiting artists spend roughly two weeks on the mountain, working alongside the institute's master sculptor, and what they finish becomes part of the trail system permanently. To date, 104 works have come out of this program, made by sculptors representing 50 countries, including Lithuania, Latvia, England, the Czech Republic, Ukraine, Egypt, Greece, and Chile.
That is not a small claim for a town the size of Brookline. Most towns with a public art collection got it in one batch, a grant, a donor, a single installation year. This one has been assembled one September at a time since 1998, when local benefactor Paul Andres and sculptor John Weidman founded the institute on what used to be a ski hill. Before it was a sculpture park, that same slope was the Brookline Ski Tow, then Musket Mountain, then Big Bear Mountain. The lodge at the bottom still does the same job it always did: it's where you check in before you go up.
The park now covers 140 acres and 12 miles of trails, making it the largest outdoor sculpture park in New England by acreage. All of it is free, every day of the year, no ticket, no gate.
What You Can Actually See This Month
The working studio area near the top of the paved access road isn't always open to visitors. Artists need room to concentrate, and in past symposium years the viewing area has closed for stretches, sometimes with little notice, when spectator safety required it. If you're planning a trip specifically to watch the carving in progress, check the Andres Institute's website before you drive over.
You don't need the studio to be open to get something out of this month, though. A dozen sculptures are visible right from the paved driveway itself, no hiking boots required. If you're walking the dog after work and want a fifteen-minute detour, that stretch of pavement is enough to feel the difference between a static gallery and a hill that's actively adding to itself.
Longtime visitors have something new to relearn this year too. This summer, the institute retired its old trail map and released a redesigned one with a shape and color coded difficulty system and a coordinate grid for locating specific sculptures. If you've hiked these trails for years and always found the right piece by memory or luck, the hill just got a little more organized underneath you.
The Rest of the Month Doesn't Wait for the Artists
The symposium isn't the only thing on Brookline's calendar this stretch. It just happens to be the one most residents don't know is timed at all.
| Date | What's Happening | Where |
|---|---|---|
| Sept 12 through Oct 4 | 26th Bridges and Connections Sculpture Symposium: visiting artists carve and weld on-site | Andres Institute of Art, 106 Route 13 |
| Sun, Sept 27, 11am to 3pm | Brookline Day, the town's annual community gathering | Organized by the Brookline Recreation Department |
| Sundays through October | Outdoor live music series, ongoing since May | Averill House Vineyard, 21 Averill Road |
| Sat, Oct 17, 1pm to 3pm | Fall Iron Melt: molten iron poured into hand-carved molds | AIA Welcome Center |
Brookline Day lands squarely inside the symposium window, which means the same three weeks that bring international sculptors to Potanipo Hill also bring the whole town out for the Recreation Department's annual celebration. It's not a coordinated pairing. It's just what happens when a small town's civic calendar and its art calendar both land in late September, most years without anyone planning it that way.
A few miles over, Averill House Vineyard is working through the last Sundays of a concert series that's run since May, in the barn-and-vineyard setting locals know as Brookline's Historic Ice District. The lineup has included acts like Duquette and Katie Dobbins over the summer, and the series keeps going through October before the vineyard shifts into its winter setup.
The Loud Ending
The symposium closes quietly, more or less, with a public presentation and closing ceremony around the beginning of October. The season's real finale is louder. On Saturday, October 17, between 1 and 3pm, the institute holds its Fall Iron Melt, described on its own site as the biggest fundraiser of the year. Residents carve molds in advance, pick them up at the Welcome Center, and watch molten iron get poured into them on pour day, turning a hand carved shape into a permanent six by six inch iron tile. It costs 35 dollars for members and 45 for non-members, and it's the kind of event that turns an abstract idea, sculpture as a process rather than an object, into something you can stand ten feet from and watch happen.
That's the arc of the season in one sentence. Quiet chisel work in September, a town festival in the middle of it, and a public pour of liquid metal in mid-October to close it out.
Why This Is Worth Knowing, Not Just Doing
None of this changes what Andres Institute of Art is on paper: a free, 140 acre sculpture park open every day of the year. What changes, for about five weeks each fall, is whether you're looking at a finished collection or watching one get made. Most people who live near it only ever see the first version. The version where the hill is quiet, the sculptures are static, and the whole place reads as background scenery you drive past on the way to somewhere else.
Starting next week, that stops being accurate. There will be people from other countries standing on that hill, deciding what stays there permanently. Brookline Day happens in the middle of it. A festival of molten iron closes it out. None of that requires planning a special trip so much as noticing that the ordinary drive down Route 13 has something happening on it this month that it doesn't have most of the year.
If you're the kind of person who likes knowing what's actually going on in the town you live in, not just the version on the welcome sign, this is a good month to pay attention. And if a season like this is part of why you'd never want to leave Brookline in the first place, the Morgan Moves Team spends its time in towns exactly like this one, and we're always glad to talk about what your home is worth in a market that includes towns worth staying in.
