Donate Help us tell Sunnyvale’s story The Historical Society and Museum Association is a non-profit organization run almost entirely by volunteers. The museum is open three times a week, year-round, and admission is free. How do we manage free admission while “keeping the lights on” and organizing special events such as receptions, Speaker Nights, and rotating exhibits? As you can imagine, volunteers are the backbone of the support needed to keep the museum running smoothly. Additionally, funding sources are extremely important in helping us continue to collect and preserve city history and educate our current and next generation of residents.
