Event Spaces at CMoA

Accommodating space allows for creative event design. Our event spaces are configured so that it’s easy to add space to your event in a variety of combinations to meet the needs of your event and budget. It’s possible to book initial space and add-on later as your event evolves and/or attendee numbers increase. With the museum currently open four days a week, most weekday events have virtually exclusive access to contracted space.

Gravity Ballroom

Includes the use of a back-of-house Catering Prep Space, the Ready Room (a small green room space that can be used for a variety of needs), and the Event Manager Office. Garage doors provide easy flow if you are combining with the Rotunda and/or a museum visit.
