Built in 1939 as the Ada Public Library, the Ada Arts and Heritage Center is a non-profit organization now serving as a museum featuring rotating art exhibits from local, regional and national artists. It has a vast collection of historical photographs.
The architecture is colonial revival-style, designed by Ada native Albert S. Ross. It is listed in the National Register of Historic Places. According to the registry, this building is considered "to be Ross's finest achievement. The building is virtually pristine, retaining almost one hundred percent of its original materials and also retaining its integrity of workmanship, design, feeling, and association."
The Ada Arts and Heritage Center is also available to rent for large group events such as weddings and family reunions.
