Callahan House

The Building

If you are looking for an intimate historic backdrop for your wedding, meeting, company retreat, special party or event, the Longmont's Historic Callahan House and Garden is the perfect place to create a memorable, affordable event. 

Enjoy the gracious elegance of our charming Queen Anne style Victorian house with warmly decorated French interiors wrapped in a poetic Italian garden. 

During the summer, the garden accommodates 150 guests who can celebrate amid flowers, statues, a fountain, a gazebo and dance on the large lawn under huge shade trees.

During the colder months, the house interior accommodates 40 to 45 sit-down guests and 80 open-house guests who can be warmed by ornately carved woodwork and parquet inlaid floors, and admire stained glass windows and floral and fruit painted walls in the French tradition. 

Callahan House rental includes whole House, House and Garden and Auto House, Auto House only, or Meeting Room only. Click for Catering and Facilities Information. 

The Callahan House is a historically designated home given to the City of Longmont in 1938 by honest and skillful merchants, Alice and Thomas Callahan. Learn about the Callahans and their history. The Callahan House is also host to several Special Events open to the community yearly. The garden is always open to the public when not booked for event. 

Our mission is to preserve, maintain and promote the Historic Callahan House for the use and enjoyment of the Longmont community creating memories and providing a legacy for the future.
