Six Napa Valley homes will open their doors for the Symphony League Home and Garden Tour May 19. The tour benefits the Napa Valley Symphony, celebrating its 75th year.

League organizers have put together a diverse group in age and style, from Napa to St. Helena.

The oldest, an elegant 19th century home in downtown Napa, is a registered landmark. Designed by W.H. Corlett, this Queen Anne house was one of the first in Napa to use both gas and electricity. The owner has the original plans and has adhered to them, with few exceptions, for the stunning renovation of the approximately 5,800-square-foot home. During the tour pianist Findlay Cockrell will add to the ambiance by playing piano in the historic house.

Up on Atlas Peak Road a Mediterranean home showcases an outdoor kitchen, infinity pool and magnificent views all the way to the San Francisco skyline. Designed by local architect Wayne Waechtler, this 4,700-square-foot home was built in 2002. The great room has cathedral ceilings and adjoins the large, professionally designed kitchen with Italian tile floors that extend to the outside living areas. The garden is a work in progress on this 40-acre property that has an old-fashioned barn, bocce court and a variety of oak and fruit trees.

Nestled in the redwoods on the western side of the valley near the Hess Collection Winery is the two-year-old home of an interior designer and builder. This house has an old world charm with its blend of French country and English-style architecture and an interior that captures a refined and rustic feel. The stone fireplace and sand-blasted beams accentuate a mix of both fine and country furniture and an extensive art collection.

A contemporary home in Yountville, designed in the 1960s by Gardner Dailey, overlooks a pool and vineyards beyond. The owners asked interior designer Michael Taylor to make over the living and dining rooms. Since then, local designer Thomas Bartlett has helped with several design projects. Landscape architect Thomas Church designed the garden with many pathways for strolling.

In St. Helena a sprawling ranch home on three acres is surrounded by pines and an old oak tree. Built in 1949, with later additions, this sunny home is decorated in the French country style with toile and French antiques throughout. The master bedroom and living room have 18th century wedding armoires from Normandy. Both rooms were featured on episodes of the House and Garden TV series “Double Take.” A guesthouse welcomes visitor with its lovely antiques and cherry red fabrics.

The charm of the vine-covered second home in St. Helena transports the visitor to southern France. Behind a rustic stone wall is a courtyard with a gravel path leading to a garden of climbing roses, boxwood, lavender, 50 year-old olive trees and a reflecting pool. This home, remodeled in 2003, features soaring ceilings, a cherry paneled library, warm cozy furnishings and interesting art. The interior exudes a comfortable and casual atmosphere with a touch of formal elegance.
