We are a private, not-for-profit corporation devoted to protecting Sonoma and Sonoma Valley’s historic buildings and cultural heritage. We offer preservation related events and advocacy programs.

The mission of the Sonoma League for Historic Preservation is to preserve Sonoma's historical structures, landscapes, public spaces, and natural resources through education, advocacy, and public recognition, while contributing to Sonoma's unique sense of place.

The Maysonnave House may be rented for meetings and the Maysonnave Garden is available to rent for weddings, parties, receptions, celebrations of life and other special occasions.

Research services are available in the Sonoma League's Archives, which consist of the Sonoma Historical Survey of vintage structures and the Cochran Binder Collection organized by different Sonoma Valley subjects.
