A Building Surrounded By A Lush Garden


Botanical Wonderland

The gardens at Cornerstone are an ever-changing botanical wonderland, showcasing innovative designs from international and local landscape architects and designers. The gardens were originally inspired by the International Garden Festival at Chaumont-Sur-Loire to create a cultural and creative haven, celebrating the connection between art, architecture, and nature.

Cornerstone Sonoma is thrilled to be offering garden tours. Guided by knowledgeable staff, the tour lasts one hour and is available to book Wednesday – Friday by appointment only. Garden Tours can be custom curated with additional special experiences such as; wine tastings, lunch, or pairings, to accommodate larger groups or special occasions.

Your wedding in the gardens

With a versatile indoor-outdoor venue, beautiful backdrops for breathtaking pictures, and exclusive catering, the gardens at Cornerstone is the place for a quintessential Wine Country wedding.

Imagine a walk through a private floral-lined pathway to The Lily Pond Lawn where you and your partner will say your vows in front of a breathtaking reflective pond, covered in blooming water lilies. Then enjoy an elegant outdoor dining experience under a custom-designed sailcloth tent, surrounded by white roses and stunning perennials. Dance the night away in The Garden Barn, complete with indoor string lights and large sliding doors to let in the fresh Wine Country air.

“The gardens are beautiful, tranquil and so well cared for. Lovely strolls through the different gardens, the lawn and a nice spot to relax by the lily pond.”
