The Dyer’s 9 acres provide many possible backdrops for your event. Pictured are the lawn and front patio of the Observatory.

Park-like grounds and celestial views make Dyer Observatory an exceptional venue for social and business events. The library, with its domed theater, is a perfect place for weddings, corporate functions, meetings and dinner parties. A spacious covered patio provides an open area for larger gatherings.

Also on the grounds is “Murial’s Retreat.” Nestled among the trees, the 2,000-square-foot house offers a living room-sized meeting space, three breakout rooms, a fully-equipped kitchen, and a spacious outdoor deck and patio. The house is perfect for corporate, educational, and private group retreats.

Both the Observatory ground floor and the residence are wheelchair accessible.

*Four hour minimum

Traditionally the observatory has been closed December-February due to maintenance and the high probability of cancellations due to inclement weather. Dyer Observatory’s hilltop is a few degrees cooler than below, and even a slight shower that presents no problem in Brentwood, may make our road treacherous. If you’d like to schedule an event at Dyer knowing that you might need an alternative location if the weather turns inclement, we’d be happy to make arrangements.
