The Bartholomew Foundation
The nonprofit Bartholomew Foundation was established as part of Antonia and Frank Bartholomew’s estate plan, with the intention of preserving and protecting this iconic site, the heart of the estate where Count Agoston Haraszthy launched the California premium wine business. Today, the foundation owns and operates both the 375-acre private Bartholomew Park and the Bartholomew Estate Winery, which is nestled within the park’s grounds.
