About
Haraszthy Villa

In 1861, in the heart of what was then his 6,000-acre Rancho Buena Vista, Count Agoston Haraszthy built his majestic Palladian villa, which was both his residence and where he conducted much of his wine business. The count’s original villa was destroyed; both the date and the cause of that destruction is still something of a mystery.

The site of the residence remained vacant until, near the end of her life and in ill health, Antonia Bartholomew rebuilt the villa in 1989 on the site of the original residence. She built it as a memorial to her husband Bart, with whom she had spent decades lovingly caring for this historic site, and as a tribute to Agoston Haraszthy. She thought of the two men as the “founders of Buena Vista.”

Our
Museum

The villa’s museum wing showcases the rich history of the site and of Frank Bartholomew’s amazing career as a journalist and, ultimately, chair of United Press International. It is currently undergoing restoration.

Access

Currently, the museum is not open to the public, but tours of the villa can be arranged by booking the “Antonia’s Story” tour and tasting at the winery. The experience includes a walking tour of the estate and the villa, highlighting Antonia’s magnificent contributions to the restoration of the Haraszthy-era Buena Vista buildings and our estate vineyards, the reconstruction of the Haraszthy villa, and the ultimate creation of Bartholomew Park.

Concerts &
Gatherings

As part of our mission to tell the story of the historic structures within the park, we collaborate with two other nonprofits, the Sonoma Valley Museum of Art and Music in Place. In Q1 of 2025, we hosted a mid-winter, 8-concert series, alternating between the museum and the Haraszthy villa. Due to the ongoing refurbishment of the museum and villa, most of our programs are on pause. We hope to resume them soon.
