Join us for an open house as we celebrate 100 years of our building being open. You’ll have the chance to meet local authors, historians, archivists, and artists, attend presentations, and explore displays, including one featuring artifacts on loan from the Petaluma Historical Library and Museum.
Books will be available for purchase, and building tours and children’s activities are scheduled throughout the afternoon.
Mayor Kevin McDonnell will help cut the very large birthday cake at 1pm.
