National Register of Historic Places in Sonoma County
The Hotel La Rose has a threefold significance. It stands as one of the major accomplishments of the Italian stonemasons of Sonoma County working around the turn of the 20th century as well as being an exponent of the historically important stone industry in the county, that before its 1 decline after 1913, was the major contributor of paving stones for San Francisco streets. The La Rosa Hotel is also a representative of the Hotel Era which in Santa Rosa began with the coming of the railroad in 1870 and declined after 1936 when all passenger traffic was terminated and automobile took precedence.
