Host Your Event at a Historic Boulder County Landmark

Built in 1896, the Altona Grange is a designated Boulder County Historical Landmark. Built in a similar style to frame homes and schoolhouses from the plains in the late 1800’s, on an acre of land, the Altona Grange features original hardwood floors, tall ceilings, large windows, and charming community touches. The Altona Grange has the charm of a historic meeting place along with the modern amenities needed for hosting celebrations and events.

Main Floor

There is a main hall, stage, two restrooms, and coat room. The main hall is 50′ X 24′ and the raised stage is 16′ X 29′. The stage features an optional vintage, hand-painted backdrop and is perfect for hosting a ceremony, serving food, presenting musicians or speakers, and additional seating for guests.

Ground Floor

The ground floor has a kitchen and open space measuring 66′ X 24′. It has durable linoleum floors, a four burner range, two ovens, a microwave, plus a full-size refrigerator and full size freezer. In addition are three long prep tables. Although the kitchen is very functional and renters are encouraged to use it, it should be noted that it is not strictly a ‘commercial kitchen.’

Outdoor Space

There is an expansive outdoor landscape ideal for hosting a variety of outdoor events. There is a grassy space, a large concrete pad, and gravel parking area. You can erect a tent, bring in food trucks, or almost anything else you can think of. The stunning view of the foothills are an impressive backdrop for photos.
