We love hosting milestone moments, and an anniversary party is one of our favorites. At Bowling Brook Mansion in Keymar, Maryland, you’ll find a mix of historic character and flexible spaces that make planning simple. We’re in Carroll County, just minutes from Frederick County, which keeps travel easy for family and friends. Our restored 1872 mansion sets a warm tone the moment guests arrive.
A Flexible Anniversary Party Venue in Keymar, Maryland
We designed the layout to feel welcoming from the moment guests arrive, whether you’re hosting something intimate or inviting a larger group.
The Spaces and How Your Guests Move Comfortably
Every celebration starts with the right room. For intimate gatherings, our gorgeous 1,265 square foot space suits up to 80 guests and includes round guest tables, banquet tables for displays, and chiavari or white padded chairs. If you prefer a larger setting, the Grand Ballroom offers 3,100 square feet for dinner, toasts, and dancing, with two fireplaces and five chandelier ceiling fans that allow comfortable lighting and airflow. When the weather is kind, the 2,000 square foot lighted Rooftop Patio is a natural spot for cocktail time or late evening mingling as it overlooks the grounds. Your event also includes access to the first floor of the mansion, so guests can step into richly detailed rooms while you gather for photos and conversation.
Neighborhood and Photo Opportunities
Our property sits in Carroll County with quick access from Frederick County, which helps everyone get here without fuss. On site, you’ll have manicured lawns, scenic gardens for photos, and a tranquil water feature. Many couples like to slip out for a few portraits near the dock with its lighted double tier fountain, then head back inside to the party.
Service and Staffing During Your Event
You won’t be setting tables or moving chairs. The venue staff handle the complete setup and breakdown of tables and chairs in our 1,265 square foot event space. Event staff are on site to support the timeline you’ve planned with your caterer and other vendors, answer guest questions, and keep the flow smooth from welcome through goodbyes.
Food and Beverage Approach
You have options. Bring your own food and soft beverages for a personal touch, or request professional catering. Catering is arranged through our approved caterers list. For beverages, bar service is available through Bowling Brook Mansion. Outside alcohol isn’t permitted due to licensing, and our team will coordinate bar details with you.

What is Included With Your Booking and What to Plan Separately
Included with your rental, you’ll have guest tables, banquet tables, Chiavari or white padded chairs, and eight high top tables with black covers, plus on site private parking. For slideshows or a short program, there is a 65 inch color TV and an 8 foot projector screen available. Plan your menu with our approved caterers or bring your own food and soft drinks. We’ll help you align staffing and bar service so everything works together.
Policies That Matter for This Event
Access to the 1,265 square foot event space is a five hour window that includes setup and cleanup, which keeps the day focused and manageable. Corporate and private events receive exclusive access to the mansion for the hours listed in the event contract. Full day use isn’t automatic for non-wedding events, though additional time may be available by request based on availability. If you’re considering a late start or an extended program, we’ll talk through the best fit when you tour.
Conclusion
Our mansion was renovated in 1872 and once trained seven Preakness winners. Today, it’s fully restored with original details and elegant finishes that bring depth to every celebration. That heritage is part of what makes the ballroom glow, the rooftop patio feel open and inviting, and a simple toast feel special.
