Sonoma Plaza
Center of Sonoma
Sonoma
Built in 1835 By Mexico

Sonoma Pueblo was the chief military base of the Mexican Government in Alta California.

In 1823, Misión San Francisco Solano de Sonoma was founded. It was the the last (northernmost) of the twenty-one Alta California missions and the only one established under Mexico rule.

In 1835, General Mariano Vallejo laid out the plaza as a parade ground for Mexican soldiers stationed at Sonoma Presidio. It is the largest central plaza in California.

On June 14, 1846, the raising of the Bear Flag in the Plaza marked the beginning of the American revolt against Mexican rule.

Sonoma Plaza has been a National Historic Landmark (NHL) since 1960 when the National Historic Landmark program was established. 92 properties were immediately designated as National Historic Landmarks including seven in California. Sonoma Plaza was the northernmost California landmark.

The boundaries of the NRHP district were expanded in 1992 to include properties on Broadway and the north side of East Napa Street.

Built 1892

Brick Victorian store is of mixed Classic Revival style. The building is in fair to good condition and is used as a hardware store.

From about 1849, an adobe building was on this site. It was purchased by Frederick Duhring in 1879, and operated as the Duhring Clothing Store and agency for Wells Fargo and Company.

In 1891 he replaced the adobe building the current brick building designed by A.C. Lutgens, who designed City Hall.

An early morning fire in October 1990 completely destroyed the building. The façade was restored with the original bricks.

First Baptist Church
AKA Ames Chapel
542 1st Street East
Built 1850

This Gothic Revival building was constructed in the early 1850s as Ames Chapel. Ames Chapel was possibly the first Protestant church north of San Francisco.

Ames Chapel originally stood on Napa Street, between 5th and 6th Streets. It was moved here in 1868, and the Christopher Wren steeple was added.

In 1950, the structure was sold to the Baptist church.

Buildings that Moved

It's not just that the people of the American West are restless, the buildings themselves sometimes pack up and move when - for one reason or another - the neighborhood no longer suits them or the neighbors no longer want them or opportunity waits down the road.

And when buildings remain in place, they are often searching for their identities.

Of the buildings and structures we have visited, the original Reno Arch holds the record for number of moves. It has been moved five times since it was built in 1926.

Jax Truckee Diner holds the distance title. The building moved from New Jersry to Pennsylvanis in 1948, then from Pennsylvania to Califonia in 1992.

Probably the most ambitious relocation occurred on July 4th 1904, when the Southern Pacific Railroad loaded most of the town of Wadsworth, Nevada, onto rail cars and transported the town thirty miles west to create a new town which became known as Sparks.

Leese-Fitch Adobe in Sonoma 11 June 2005

Sonoma Plaza Historic District
Leese-Fitch Adobe
487 First Street West
Built 1841

Built in 1841, by Jacob P. Leese, a brother-in-law of Vallejo, this house is a two- story adobe in the Monterey Colonial style with a wooden balcony across its front. This balcony may have been reduced in width at a later period.

Originally the balcony was supported by two- story columns made of ship's masts. From June 18^9 to October 1851, the Pacific Division Headquarters of the War Department, commanded by General Persifer Smith was located in Sonoma in the structure. From July 1851 to January 1852, except for a period of duty in Oregon, Companies "A" and "E", 1st United States Dragoons commanded by Brevet Major Phillip H. Kearny, Jr., was stationed in Sonoma.

Many junior officers, later to achieve fame and advancement, were associated with the adobe during the military period; including Colonel Joseph Hooker, later known as "Fighting Joe" Hooker, Ulysses Grant, Andrew Smith, Lieutenant William T. Sherman, General Gibbs, John C. Fremont, and Kit Carson. The building is in poor condition and houses an art gallery and tavern on the first floor and small patio, the apartments on the second floor and are not occupied. The structure is in need of rehabilitation.

Constructed by 1860 by Frederick Duhring, the structure was originally a modest two-story frame building. Later, a Duhring daughter, Agens, married Judge Thomas Denny and lived in the house; who probably in the early 1920's added to the house and modified it to colonial-revival style. In 1960, on Judge Denny's death, the house was sold to Albert Domerigue.

Ray Adobe in Sonoma 10 June 2005
Sonoma Plaza Historic District
Ray-Adler Adobe
AKA Rays Hotel
205 East Spain Street
Built 1846

The house was built by John C. Ray, an American Settler. In 1848 the first section of wood was erected and in November 1851, the original section was incorporated with the more recent adobe half of the residence at a cost of $4,000.

The two-story structure has a hipped roof and a borad veranda around all four sides. The front section of the adobe has 22 inch thick walls and the rear section of the structure is of redwood.

The adobe section, added in 1851, was evidentally added for rental purposes and the building was called Ray's Hotel. The dirt for the adobe came from across the street.

In 1851, Lewis Adler purchased the structure and it continued under the name Ray's Hotel. On Adler's death, the property went to his wife and on her death, it went to Amelia Adler Bates, who sold it in 1902.

The structure is well preserved and apparently little altered. It is now used as a private residence.

In 1851, the house was used as the Officers' Mess for Colonel Stevenson's detachment; the New York Volunteers, the 160th Regiment.

On May 6, 1851, Masonic Temple Lodge number!4, received its charter. A Masonic meeting hall was established in the upstairs of the Ray House, Colonel Stevenson was the first Grand Master of the Grand Lodge in California.

Members of Lodge 14, meeting in the structure, included Stevenson, Johnston, Hooker, Sheridan, Grant, Braekett and Sherman; most junior officers at the time and later to gain fame in the Civil War.

Later, Heinrick Schleimann, often called the Father of Archeology, lived in the house while courting Adler's sister. Schleimann is known for his discovery of ancient Troy.

When the Sonoma Plaza boundaries were expanded in 1992, the Ray-Adler Adobe was listed again with a rewritten description.

245 East Spain Street: Cooke House 9 August 2026
Sonoma Plaza Historic District
Dr. Taylor House
245 East Spain Street
Built 1852

This structure greatly resembles the enclosed adobes of 1847-1851 period. However, it has always been of frame construction.

The house, of Monterey Colonial Style, has a long front porch and has wide horizontal redwood siding with butt joints on the front of the house which is original. Redwood stumps were utilized as a foundation for the front porch which were replaced in recent years. The house has been restored with a garage and a rear wing added about 20 years ago.

The property was part of the original grant to Don Marieno G. Vallejo. The property has also been owned by Lilburn W. Boggs, the American Alcalde of the District of Sonoma, Territory of California, who sold the property to John G. Ray on January 11, 1848. Exactly when the house was constructed is not certain.

The earliest occupant was named Cook (or possibly Cooke) who sold the house in 1861 to a wagon maker named Hope.

A Martin E. Cooke, came to Sonoma in 1852 as General Vallejo's attorney. In 1856, he purchased the Blue Wing Inn and later served as State Senator.

In the 1940's a Fred Jenner owned the house and sold it to Dr. Taylor in the 1950's, who restored the house. The house is in excellent condition.

In 1850, Lewis Alder moved into the new frame building which was known as Meyer and Alder's Store. The building was located on East Spain Street across from the Blue Wing Inn.

In 1856, it was purchased by another merchant and moved to the southwest corner of First Street East and Napa Street.

The building was later purchased and moved to 256 East Spain Street for use as a residence. Later, probably in the 1880's a second story was added.

Built c1896

The nomination form reads: "A Victorian structure, classic revival, originally called Weyl Hall, of wood construction. Originally a theater was located on the second floor of the structure. Purchased by Sebastiani who rebuilt the structure and probably added the yellow stucco finish with white trim. Presently, the structure is used as a hotel and bookstore. Date of construction is uncertain. The hotel keeper thinks that the structure was built about 1896."

When we photographed the building, it housed the Sonoma Hotel and the highly-regraded restaurant, The Girl and the Fig.
