Treat Your Holiday Guests with a Visit to Old Mission San Jose Museum and Gift Shop. We will be OPEN Thanksgiving Weekend, Friday through Sunday! With family and friends visiting for the Holidays, consider exploring the treasure in our own backyard – Mission San Jose, a Nationally Registered Historic Place and a California State Historic Landmark. Shop early for those unique gifts: books, jewelry, ornaments, apparel, religious items, creches, and more. And you can still buy 225th Anniversary commemorative items while they last. We have coffee mugs, decanter & wine glass sets, heritage wine glasses, beer mugs, and more. Selected items will be discounted 25% from November 18th through December 31st.
