You’ve probably driven past it. If you live anywhere near the West End of Portland, Maine, the stony, imposing presence of the church at 156 High Street is just part of the furniture. But there’s a specific quietness to the Greenough Chapel Williston-Immanuel United that hits differently once you actually step inside. It isn’t just about the architecture, though the granite and the stained glass are obviously stunning. It’s about the layers of history—the literal merging of two distinct congregations—that created this specific atmosphere.
Portland has plenty of old buildings. Some are breweries now. Some are condos. But this spot? It stayed a sanctuary.
What Actually Is the Greenough Chapel Williston-Immanuel United?
To understand the chapel, you have to understand the messy, human reality of church mergers. Williston-Immanuel United Church is the result of a 1972 union between the Williston Congregational Church and the Immanuel Baptist Church. Think about that for a second. Two different traditions, two different sets of "this is how we've always done it," deciding that they were better off under one roof.
The Greenough Chapel specifically serves as a more intimate pivot point within that larger complex. Named after the Greenough family—specifically Byron Greenough, a wealthy merchant whose name is plastered all over 19th-century Portland records—it was designed to be a smaller, more manageable space than the massive main sanctuary.
It’s cozy. That’s the word.
While the main sanctuary feels like a place where you’d expect a massive pipe organ to blow your hair back, the Greenough Chapel feels like a place where you can actually hear yourself think. It’s used for smaller services, contemplative gatherings, and community meetings. Honestly, in an era where everything is loud and digital, standing in a room built with 1800s intentionality feels like a bit of a cheat code for your mental health.
The Architecture Isn't Just "Old"
People see Gothic Revival and just think "spooky" or "fancy." But the design of the Greenough Chapel within the Williston-Immanuel United framework is actually quite clever. Francis Fassett, the architect who basically rebuilt Portland after the Great Fire of 1866, had his hands all over this. He didn't just want a box for people to sit in. He wanted height. He wanted light that felt heavy.

The stained glass here isn't the flashy, neon-bright stuff you see in modern builds. It’s deep. Amber. Cobalt. When the sun hits the High Street side of the building in the late afternoon, the chapel glows in a way that makes you realize why people spent so much money on colored glass before electricity was a thing.
Why People Get This Place Wrong
There’s a common misconception that these old Portland chapels are just museum pieces. Dead air. Dust.
That's not what's happening at Williston-Immanuel.
The congregation is known for being aggressively inclusive. You’ll see the Pride flag. You’ll see posters for social justice initiatives. It’s an Open and Affirming (ONA) church, which, if you aren’t familiar with church-speak, basically means they aren't just "tolerating" people—they’re actually welcoming them. This creates a weird and beautiful contrast: you’re sitting in a room that looks like it belongs in a 19th-century period piece, but the conversation is about modern systemic reform and community food security.
It’s a vibe.
And let’s talk about the Greenough name for a minute. Byron Greenough wasn't just some guy with a chapel. He was a pillar of the community who made his fortune in the hat and fur trade. In the 1800s, Portland was a hub of global trade, and the wealth from that trade built these stones. When you stand in the chapel, you’re standing on the literal profit of Portland’s golden age of commerce. It’s important to remember that these spaces weren't just "spiritual"—they were statements of civic pride.

The Practical Reality of the Space
If you’re visiting or looking for a space, there are things you should know. It’s not a sterile environment. It’s an old building. It has creaks. The acoustics in the Greenough Chapel are sharp—perfect for unamplified speech or a solo acoustic guitar.
- Location: High Street, right near the Portland Museum of Art.
- Accessibility: Like many historic Portland buildings, it has its quirks, but the church has worked hard to make the main levels accessible.
- Usage: It’s a multi-use space. You might find a 12-step meeting there one night and a liturgical reading the next morning.
The "United" in the name isn't just a label; it’s a functional description. They are affiliated with both the United Church of Christ (UCC) and the American Baptist Churches. That’s a lot of theological ground to cover, but it works because the focus is on the local community rather than distant denominational squabbles.
How the Chapel Survived the "Death of the Church"
You’ve seen the headlines. "Religion is dying." "Church attendance is at an all-time low."
So why is the Greenough Chapel Williston-Immanuel United still there?
Because they leaned into the building’s role as a community anchor. They didn't lock the doors and wait for Sunday. They opened them. By hosting the Wayside Food Programs and various community concerts, they turned a "sacred space" into a "useful space."
There’s a specific kind of stone used in the construction—puddingstone and granite—that is famously durable. It’s almost metaphorical. The building was designed to outlast the people who built it, and so far, it’s doing exactly that. It survived the urban renewal era of the 60s and 70s that tore down so many other beautiful Portland structures.

A Note on the Stained Glass
You really have to look at the windows. Seriously.
The windows in the chapel area and the connecting corridors are often overlooked in favor of the massive ones in the main sanctuary, but they are gems of 19th-century craftsmanship. They aren't just religious scenes; they are masterpieces of glass-firing. The depth of color achieved back then is incredibly hard to replicate today without it looking "flat."
If you go, look for the way the lead lines create a secondary pattern that doesn't always match the colors. It’s an art form that is basically extinct in modern construction because it’s too expensive and takes too long.
What You Should Actually Do
If you’re interested in the Greenough Chapel Williston-Immanuel United, don’t just read about it.
- Walk the perimeter first. Look at the stonework on the High Street side. You can see the transitions where the building was expanded or repaired over the decades.
- Check the community calendar. Don't just show up for a service if that’s not your thing. Look for a concert or a public lecture. The acoustics are the real star of the show.
- Respect the silence. Even when there isn't an event, if the doors are open, step in. The temperature drops about ten degrees, and the street noise of Portland fades to a hum.
- Look into the history of the merger. If you’re a history nerd, the archives of how Williston and Immanuel became one are a fascinating study in 1970s sociology.
This isn't a museum. It’s a living part of the West End. Whether you’re there for the architecture, the history of Byron Greenough, or just to find a quiet corner in a busy city, it’s one of those rare places that actually lives up to its own history.
Final Practical Insight
The best way to experience the chapel is during the "shoulder" hours—early morning or late afternoon. The light is the primary narrator of the space. Because of the orientation of the building, the shadows in the Greenough Chapel move in a way that highlights the textured walls and the heavy timbering of the ceiling. It’s a masterclass in pre-electric interior design.
If you’re planning a visit, park in the nearby garages or use the street parking on Congress Street; High Street can be a nightmare for idling. Walk over, take in the facade, and then find the smaller entrance that leads toward the chapel. It’s a transition from the chaotic energy of downtown Portland into something much more grounded.
Don't overcomplicate it. Just go in and sit down. The building does the rest of the work for you.
