Oakland Heritage Alliance is 35! Join old friends and new, celebrating our love of Oakland’s architecture, history, cultural riches. And what better place to celebrate OHA’s endeavors than at a party in the beautiful Craftsman Dining Hall of the Dimond District’s historic Altenheim? This not-to-be-missed event will be a rare chance to enjoy an award-winning preservation treasure— an Oakland landmark on the National Register of Historic Places; festivities begin by unveiling a new landmark plaque. Join us for food, drink, tours, live music, wine raffle and more! Proceeds benefit the continuing work of OHA at a critical time of change in our city! First 50 who reserve will receive a $10 discount.
