Park-like grounds and celestial views make Dyer Observatory an exceptional venue for business events. The library, with its domed theater, is a perfect place for 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, one breakout room, 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 Muriel’s Retreat are wheelchair accessible.

Muriel’s Retreat was built as the residence for the original Observatory Director, Dr. Carl Seyfert, and his family in 1953. It is named in memory of Muriel Mussels Seyfert who was Carl’s wife as well as an accomplished astronomer, painter, and equestrienne.

Traditionally the observatory is 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.
