From the Guidebook:
about 1850 by Don Salvador Vallejo, this adobe adjoined
his first Sonoma dwelling built in 1836. Occupied by
various pioneers, it was the house in 1861 of Dr. Victor
J. Faure, vintner of prize-winning wines made from the
grapes of the Vallejo family vineyards. Later, it became known as the "Swiss Hotel" because of its use for hotel and restaurant purposes.
