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 exterior patio provides an open area for larger gatherings.

Also on the grounds is the “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 and the residence ground floors are wheelchair accessible.

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 can 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.
