The Boylston Room East
The Boylston Room East has many elements of the original mill, including century-old maple floors, hardwood pillars and steel beams. Seven north-facing mill windows fill the space with soft natural light. This 2,600 squre foot venue can accommodate up to 150 guests for a seated dinner, or 300 guests for a ceremony.
The Boylston Room West
The Boylston Room West is a bright and spacious room with both brick and steel pillars across a modern polished concrete floor. Overlooking the patio and front garden, it’s a perfect canvas for any event. At 3,800 square feet, this venue can accommodate up to 300 for a seated dinner, or 260 seated on the north side with a large dance floor on the opposite side of the room.
The Waterfront of the Lower Mill Pond
The waterfront of the Lower Mill Pond is a fantastic spot for an outdoor ceremony and is a lovely photography location. Located just behind the mill, the wildflower meadow offers spectacular views of Mt. Tom and the Holyoke Range.
The Garden Courtyard
Both the Boylston Room East and the Boylston Room West look out onto the Garden Courtyard. The Courtyard is located next to the East Entrance of Keystone Mill, and it’s a perfect spot for a social hour, late-night snacks or a dramatic send-off.
The Wedding Suites
Our two spacious wedding suites give both parties a relaxing day of preparation at the venue. With three hair and makeup stations, a private bathroom, cozy robes, ample seating, and fully stocked wedding emergency kits, you have everything you need to get ready for your day in style.
