Sonoma Overlook Trail stewards and the Sonoma League for Historic Preservation are sponsoring a downtown history walk and garden party at Maysonnave House on Saturday, Sept. 22, from 3 to 5:30 p.m., to raise money for the trail’s current rehabilitation project and regular maintenance.

Registration cost is $50 per person, which includes finger foods, a glass of wine and a leisurely afternoon in the beautiful Maysonnave fall gardens. Register online at https://conta.cc/2OUdMBY.

Participants can pick up self-guided walking tour materials at the historic house, 291 First St. E., and learn about the Plaza’s colorful and intriguing history from league-member Chuck Bingham.

Barbara White Perry, Sonoma Treasure Artist and author of “Drawing Sonoma,” will be on hand and has donated a framed drawing of Maysonnave House and a special bottle of Buena Vista Private Reserve Zinfandel from her vineyard for a raffle.

Volunteer trail stewards will also update participants about the progress of the Overlook trail rehabilitation project.
