Why Mill 1?

  • Mill 1 is gorgeous. When we created the event space, we didn’t mess with perfection: we sandblasted the original brick, exposed the original high-ceiling pine beams, and refinished the original gleaming maple wood floors. We also added a stunning custom-designed bar and modern amenities. So not only will you get the historic feel of the generations that filled the space before you, you will get a uniquely serene, beautiful, natural backdrop that can be customized to reflect your personality and style.
  • Your wedding photos and videos will look fantastic, no matter the weather, no matter the time of day, no matter the season. We’re across the street from a state park and the historic Holyoke Canal Walk, both of which feature incredible outdoor and industrial backdrops. And our wide variety of indoor, well-lit spaces ensure dry, comfortable guests while offering stunning photos you will cherish for decades.
  • Our Event Managers are highly experienced and love working to make your special day a reality. They are deeply grounded in managing details, but they lead from the heart, which is exactly what you want for the biggest party you’ve ever planned. We put all our love and care into helping you manage your unforgettable event.
  • We take food very seriously. Because personal and tailored food choices make events special and memorable, Mill 1 doesn’t limit you to one in-house caterer. Choose among our variety of five caterers, who consistently provide exceptional service and delicious fare.
  • We’re green. We produce electricity onsite using a renewable resource (water) making every event at Mill 1 Zero Net Energy. We’re the most eco-friendly site for your celebration!
