How long does a temporary building last when nobody has set a date to replace it? The timber pavilion on Free Street has about five weeks left in its first season.
The Portland Museum of Art opened PMA | AMP, a free open-air pavilion, on Friday, October 2, 2026, on the future site of its planned expansion. The lot is 142 Free St., next to the museum's main building. The structure is built to be taken apart, moved and reused once construction starts on that wing. In September, Mainebiz reported that no timeline for groundbreaking had been made public. So the pavilion has no announced end date. What it does have is a season. The museum's posted schedule opens AMP from May through November and lists it as "closed seasonally" after that. That leaves the Arts District's newest public space with a first year of roughly two months, with about five weeks of it still ahead.
What went up at 142 Free Street
The lot used to hold the Children's Museum & Theater of Maine, which moved to Thompson's Point. In its September 2026 report, Mainebiz said the old building was razed the previous September. What stands there now is a 4,200-square-foot timber pavilion designed by LEVER Architecture, the firm also designing the PMA's planned 60,000-square-foot expansion.
Two Maine companies were partners on the project: Portland design-build firm Woodhull and WholeTrees, which operates a timber mill and fabrication facility in Ashland. The museum says the structure uses largely Maine-sourced timber and regional materials. Portland artist Jenna Pirello painted a site-specific mural for the space.
The museum also built in something closer to a daily-use space than a gallery. It calls it an "Outdoor Office," with free Wi-Fi and public seating meant for lingering. In the PMA's announcement, Executive Director Mark Bessire described the goal as a space that is "welcoming, experimental, and immediately useful for the community."
Temporary, with no end date
The pavilion is temporary by design. The building it stands in for has been planned since 2022, when the museum launched its campus expansion and unification project. The museum's Blueprint page lays out the phases, starting with the 142 Free Street development, followed by further campus unification and then land investment. Its "What's Next" section gives no construction start or finish dates. Mainebiz describes the expansion as a $100 million project and says the museum is still raising money for it.
The pavilion comes down only when construction starts, and no start has been scheduled. The one fixed date on its calendar is the seasonal close at the end of November, and that is the date that matters for Portland right now.
The museum is also treating the pavilion as a trial run. It says the temporary space lets it test ideas that will shape the larger reimagining of the museum. LEVER founding principal Thomas Robinson, quoted in the same release, said that opening the site during the design process creates "an opportunity for public participation that will directly inform and shape the future expansion." If that holds, this fall's foot traffic is feedback on a building that doesn't exist yet.
The November window
The pavilion keeps the museum's regular hours, and those changed in October. The PMA began closing on Mondays starting October 19.
| Day | PMA | AMP hours |
|---|---|
| Monday | Closed |
| Tuesday through Thursday | 10 a.m. to 6 p.m. |
| Friday | 10 a.m. to 8 p.m. |
| Saturday and Sunday | 10 a.m. to 6 p.m. |
The museum notes that hours may vary and points visitors to portlandmuseum.org for updates. Friday has the latest hours, and Fridays are also when museum admission is free from 4 to 8 p.m.
The pavilion's best night next month is likely Friday, November 6, when Creative Portland's First Friday Art Walk runs from 5 to 8 p.m. across the Arts District. AMP opened on October's Art Walk night with a drop-in monotype tree-print activity and a set from DJ Jams FRREVER. November's Art Walk will be the only other one before the seasonal close. The December walk, on December 4, falls after the pavilion's posted season ends.
The same Friday has a quieter option inside the museum. "Noontime Talk: Birding in the Galleries" runs from noon to 12:30 p.m. on November 6, and a Wyeth gallery tour follows on Saturday, November 7, from 11 to 11:45 a.m.
The museum's list of planned collaborators shows how widely it means to draw from the neighborhood. It names Creative Portland, Mayo Street Arts, WMPG Radio, the City of Portland, Maine Outdoor Film Festival, Friends of Congress Square Park, State Theatre, Flat Iron Coffee and Classical Uprising. The PMA's site lists AMP programming as it is scheduled.
The blocks around it moved this fall too
The pavilion sits in the middle of an Arts District that changed in the weeks around its opening, and the changes run up and down Congress Street.
Bad Neighbors, at the corner of Congress and Brown streets, opened in late August in the former Soakology space. It comes from Dave Aceto, Nicole Costas and Dennis Gaines, the owners of Arcadia. Portland Food Map describes a listening bar seating 75, with a counter wrapped around a dual-turntable DJ station in the middle of the room. Gaines did the sound design. Costas built a list of 15 cocktails, and chef Erasmo Benavides developed the food menu with consulting chef Evan Richardson. At opening, the posted hours were Wednesday through Sunday, 5 p.m. to midnight.
Paak opened in September at 650 Congress St., near Longfellow Square. It is a fast-casual cafe serving bowls and smoothies, from owners Praewpran Yiamjanya and Patrick Udomsay, according to Portland Food Map.
One Congress Street space is ending its run in the same stretch of weeks as the pavilion. Botanically Curious, Paula Kersch's educational apothecary on the first floor of the Masonic building at 419 Congress St., plans its last day on November 22, according to Portland Food Map. The shop opened on April 5, 2024. Kersch described it as an educational apothecary and "third space," and she is selling non-Botanically Curious stock at 40 percent off before closing.
Then there's the State Theatre, whose calendar fills in the rest of the month. Punch Brothers play November 11, and The Walrus' Beatles Night runs November 27 through 29. The Beatles Night dates land in the last days of the pavilion's posted season.
After the pavilion closes for the season
When AMP goes quiet in December, the museum next door picks up the slack. The exhibitions inside are scheduled to cover the winter.
"Sascha Braunig: Wrist Painter" opens November 13 and runs through March 14, 2027. "Holding the Light: Contemporary Wabanaki Photography" opens December 11 and runs through April 25, 2027. "Eve Biddle: Wonderlands" continues through January 24, 2027, and "Passages in American Art" through January 1, 2027.
Two December evenings round out the season:
- Free Friday December Lights, Friday, December 11, 3 to 8 p.m., with holiday card-making and gift-wrapping activities.
- Third Thursday: December Lights, Thursday, December 17, 10 a.m. to 8 p.m. Its program includes Friends of Congress Square Park's S'mores Night from 4 to 6 p.m.
The State Theatre also has Old Crow Medicine Show on December 8 and The Fogcutters Big Band Super-Fantastic Christmas Extravaganza! on December 12.
The pavilion's own calendar for the rest of the season is a matter of weeks. The museum's announcement calls the structure on Free Street an early preview of its broader expansion. As of Mainebiz's September report, no groundbreaking timeline for that expansion had been made public. For now, the timber pavilion is open Tuesday through Sunday, and November is the month to see it.
