You’ve probably seen it if you've ever spent more than five minutes in downtown Buffalo. It’s that sleek, white-pinstriped tower standing tall at 345 Main Street. Most people just call it the M&T building and keep walking. But honestly? One M&T Plaza Buffalo NY is way more than just a place where bankers move money around.
It’s a piece of architectural DNA.

If you look closely at those narrow windows and the way the base arches upward, you might get a weird sense of deja vu. There's a reason for that. This building was designed by Minoru Yamasaki. Does that name ring a bell? It should. He’s the guy who designed the original World Trade Center twin towers in New York City.
The World Trade Center's "Little Brother"
People in Buffalo love to brag that One M&T Plaza was basically a prototype for the Twin Towers. That’s not entirely a myth. Completed in 1967, this 21-story tower was Yamasaki’s chance to play with the "New Formalist" style before he went mega-scale in Manhattan.
The similarities are kinda spooky.
- Those super-slender windows? Yamasaki famously had a fear of heights. He designed narrow windows so people inside would feel more secure, not like they were dangling over a cliff.
- The "forked" columns at the base? Look at old photos of the WTC lobby. It’s the same language.
- The steel? It came from Bethlehem Steel right here in Western New York.
It’s roughly 318 feet of Buffalo history. While it isn't the tallest building in the city—that honor goes to Seneca One—it’s arguably the most elegant. It’s got this weirdly light feeling for a skyscraper, almost like it’s floating on its marble base.
What’s Actually Inside One M&T Plaza?
Besides the obvious (it's the world headquarters for M&T Bank), the building is a bit of a fortress of local commerce. It spans an entire city block. Inside, you’ve got about 800,000 square feet of office space.
But it’s not all cubicles and spreadsheets.
The 19th floor is actually pretty legendary. It was recently overhauled and is occasionally open for "Doors Open Buffalo" events. It’s got these massive executive dining rooms and a boardroom that looks like something out of a 1960s Bond movie, but modernized.
The lobby is where the real flex is. We’re talking 35-foot ceilings and Vermont Verde Antique green marble. A few years back, they actually had to do a massive restoration because the original marble was starting to bow and crack—turns out 50 years of Buffalo winters is rough on even the best stone. They finished the $20+ million face-lift in 2023, and it looks brand new.

The Plaza is the Real Star
If you’re a local, you don't go to One M&T Plaza for the banking. You go for the "Plaza Event Series."
For over 50 years, they’ve been doing these free lunchtime concerts in the summer. It’s one of the few things that actually makes downtown feel alive during a random Tuesday in July. You get food trucks, live jazz or rock, and hundreds of people sitting on the ledges by the fountain eating overpriced tacos. It’s great.
A Few Quick Stats
- Height: 318 feet (97 meters).
- Floors: 21.
- Cost to build: Around $16 million in 1967 (which is roughly $150 million today).
- Materials: White and green marble, plus a whole lot of local steel.
Why It Still Matters in 2026
In an era where everyone is working from home and downtowns are struggling, One M&T Plaza stays relevant. Why? Because M&T Bank didn't bail. They’ve doubled down on Buffalo. While other banks moved their HQs to Charlotte or NYC, M&T kept their "brain" right here on Main Street.
It’s a symbol of stability.
Also, it’s just a cool building to look at. In a city filled with heavy, dark masonry like the Guaranty Building or City Hall, the M&T tower is bright. It’s airy. It’s a reminder of a time when Buffalo was looking toward a high-tech, mid-century future.
Actionable Tips for Visiting
If you want to experience One M&T Plaza Buffalo NY for yourself, don't just stare at it from the Metro Rail.
- Visit in July: Seriously. The lunch concert series (usually 12:00 PM to 1:00 PM) is the best way to see the plaza in action.
- Check the Lobby: You can usually walk into the main banking hall during business hours. The scale of those arched windows from the inside is wild.
- Park Smart: If you're heading there for an event, the M&T parking ramp on Washington Street is usually the go-to, but it fills up fast.
- Photography: The best angle is from the corner of Main and Eagle Streets right as the sun is hitting the white marble in the late afternoon.
Keep an eye on the "Doors Open Buffalo" schedule for the year. That is usually your only ticket to getting into the upper-level executive suites and seeing the view of Lake Erie from the top, which is easily one of the best views in the 716.
