Ralston made his first million dollars from his investment in
Nevada's
Comstock Lode. His dream was the construction of the
Palace Hotel in San Francisco at the corner of
New Montgomery and
Market. He spent $5 million on its construction, draining his banking empire in the process.
John P. Gaynor was the architect and had been instructed by Ralston to study European luxury hotels for inspiration. The hotel opened on October 2, 1875. The hotel had early elevators or "rising rooms" and electric call buttons in the rooms. The hotel survived the
1906 earthquake but was destroyed in the fire that followed. It was rebuilt and reopened in 1909. off the main corridor to the left. In 1871, following a severe drought in California, Ralston initiated work on the surveying for an irrigation scheme in the
San Joaquin Valley, and his lobbying was successful in securing the passage through Congress in 1873 of an act to set up a Water Commission to advise on the
irrigation of California. Ralston was a possible co-conspirator in the
Great Diamond Hoax. ==Collapse of his financial empire==
