If you drove down Newton Street this morning before nine, you passed a lawn already filling with cars that don't usually leave the garage. Today is BMW Day at Larz Anderson Park, gates open at 9 a.m., spectator tickets sold at the front gate, cash or card or Apple Pay. It is one Sunday in a run that stretches from spring through fall, and if you look at the full schedule, something becomes obvious: this isn't a museum bolting car shows onto a park calendar. It's a family's Sunday habit that the neighborhood never let go of, even after the family was gone.
That distinction matters more than it sounds like it should, because it explains why the calendar reads the way it does, why the rules are shaped the way they are, and why across town, a very different piece of public land runs on the exact same logic.
A Family's Sunday, Before It Was a Calendar
The Larz Anderson Auto Museum bills itself as home to America's oldest car collection, and the claim traces back to one vehicle: an 1899 Winton 4-hp Runabout that Larz and Isabel Anderson bought and kept, then added to over the following decades until the collection reached 32 motorcars and horse-drawn carriages. The Andersons didn't build a museum. They built a private collection on a private estate, and on Sunday afternoons they opened the doors of their carriage house so the public could come look. That habit predates any formal event calendar. It was just what the family did on Sundays.
The estate's public role went beyond cars. Records from the museum describe the Andersons hosting plays, dog shows, and informal gatherings for early automobile enthusiasts on the same grounds, a detail that matters if you've ever wondered why leashed dogs are still welcome at the museum's lawn events today. It isn't a modern accommodation bolted onto an old property. It's a continuation of what the lawn was already used for.
When Isabel Anderson died in 1948, the collection passed to the Veteran Motor Car Club of America, and that stewardship is what eventually became the Larz Anderson Auto Museum. The museum didn't invent the Sunday tradition. It inherited one that was already decades old and gave it a name.
The Roster Reads Like a Guest List
Walk the lawn on any themed Sunday and you'll notice the calendar isn't organized the way a typical car show would be. It doesn't group by era or by price point. It groups by marque, the way a personal collection would, because that's what it grew out of. German Car Day. British Car Day. Corvette Day. Tutto Italiano for the Italian marques. Porsche Day already ran this year, on July 26, with the lawn full of German sports cars parked among the museum's permanent Carriage House collection. The format has the feel of a family reunion where everyone brings the same last name, because in a sense, that's exactly what it is.
Here's what's left on the 2026 calendar through early fall:
| Date | Event | Time |
|---|---|---|
| Sun, Aug 16 | BMW Day | 9:00 a.m. |
| Sun, Aug 23 | Swedish Car Day | 9:00 a.m. |
| Sun, Aug 30 | Retro Revival | 9:00 a.m. |
| Sun, Sept 13 | Mercedes Day | 8:00 a.m. to 1:00 p.m. |
| Sun, Sept 27 | European Motorcycle Day | 8:00 a.m. to 1:00 p.m. |
| Sun, Oct 4 | Japanese Car + Motorcycle Day | 8:00 a.m. |
| Sat, Oct 10 | Cars + Coffee | 8:30 to 11:30 a.m. |
A few things stay consistent no matter which Sunday you show up. Dogs are welcome on the lawn as long as they're leashed, though they aren't allowed inside the museum building itself unless they're service animals. Alcohol isn't permitted anywhere on the grounds, a rule the museum enforces at the request of the Town of Brookline and the Brookline Police Department. Spectator tickets never sell out, since they're only sold at the gate the day of. And starting this year, museum members get a 48-hour early registration window for their own vehicles before the general public can sign up, a small perk that signals the events are still built around a community of people who show up regularly rather than a one-time audience.
The Same Idea, Wearing a Different Coat
Head over to the Brookline Reservoir, which sits along Route 9 on Boylston Street, and you find a piece of land that started life for an entirely different private purpose but ended up shaped by the same instinct: something built to serve a narrow function eventually opened itself to everyone.
The reservoir was built in 1848 as part of the waterworks system supplying Boston with drinking water, decades before it belonged to any resident who might jog past it today. The gatehouse at the northeast end, which still houses the seasonal public restroom, dates to 1887. The 32-acre park wrapped around the water is now a 1-mile crushed stone loop, level enough to be wheelchair and stroller accessible, and it's part of the Emerald Necklace, the roughly 1,100-acre chain of parks Frederick Law Olmsted designed to link Boston's green spaces together.
Like Larz Anderson Park, the reservoir carries rules that trace back to what it originally was rather than what a planning committee might design from scratch today. Leashed dogs are welcome, with water fountains for both humans and their dogs positioned at the northeast and southwest corners, running from late spring through early fall. Fishing is allowed but requires a permit from the Brookline Town Office, a holdover from the water body's working past. Cherry trees line the loop and bloom in early May, a detail longtime walkers mention more often than almost anything else about the place.
The Friends of the Brookline Reservoir, a volunteer group established in the mid-1980s, still funds new trees and plantings and organizes cleanups, functioning much like the museum staff who keep the Anderson family's Sunday habit running decades after the family itself is gone. Neither piece of land was designed from the start to be a shared amenity. Both became one, and both still carry the fingerprints of what they used to be.
Stitching the Two Together
If you're building an actual Sunday out of this, the two places pair naturally. Cars + Coffee mornings at Larz Anderson run 8:30 to 11:30, early enough that you can walk the lawn, watch entries roll in, and still have most of the day left. The reservoir loop takes most walkers somewhere between 18 minutes and an hour depending on pace, an easy add-on either before or after, especially with a dog who's spent the car show on a leash and could use the open stretch of the 1-mile path to actually move.
Neither destination asks much of you. No membership is required to watch a Lawn Event from the gate. No reservation is needed to walk the reservoir loop, though the restroom and water fountains only run seasonally, so late fall visitors should plan around that. What both places offer is something harder to manufacture: a rhythm that existed before anyone thought to market it, built by people who were simply doing what they'd always done on a Sunday and letting the neighborhood in.
That's the part of Brookline that doesn't show up on a map or in a listing description. It's in the fact that a car museum's leash policy has a hundred-year-old logic behind it, and that a reservoir built to supply drinking water to another city entirely is now where half the dogs in town get their exercise. Knowing that kind of detail, the why behind the rule rather than just the rule itself, is the same instinct that goes into understanding a street, a house, or a town before you ever put an offer on paper.
If you're thinking about what it actually means to live inside a place like this, not just visit it on a Sunday, Emily Farrar works this exact stretch of MetroWest and is happy to talk through what a neighborhood's habits tell you that its listing photos never will.
