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. Please note that Murial’s Retreat is currently closed for renovation. Contact us for future available dates.

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.
