An early map noted the area as Campbell's Gap. In 1851 Martin McCarthy, who had leased the mill, built a toll road down to the Santa Clara Valley, and founded what is now Saratoga as McCarthysville.The toll gate was located at the present day intersection of Big Basin Way and 3rd St., giving the town its first widely used name: Toll Gate. In 1867 the town received a post office under the name of McCarthysville.Industry soon sprang up and at its pinnacle the town had a furniture factory, grist mill, tannery, and a paper factory. To commemorate this newfound productivity the town was renamed again in 1863 as Bank Mills. In the 1850s Jud Caldwell discovered springs which were called Pacific Congress Springs because the water had a mineral content similar to Congress Springs, in Saratoga Springs, New York. In 1865 the town received its final name, Saratoga, after the city in New York. At the same time a resort hotel called Congress Hall was constructed at the springs, named after the famous resort Congress Hall at Saratoga Springs, New York. California's Congress Hall attracted tourists to the area until it burned down in 1903.These events would eventually lead to Saratoga being listed as a California Historical Landmark in 1950.Downtown Saratoga, facing southwest at the intersection of Saratoga-Los Gatos Blvd. and Saratoga Ave and Big Basin Way/State Route 9, and Saratoga-Sunnyvale road.Saratoga became agricultural, as did much of the rest of the valley; a few vineyards and orchards from this period remain today. After World War II the town quickly became urbanized, and it incorporated in 1956 mostly to avoid being annexed to San Jose. A slogan during the campaign to incorporate the city of Saratoga was "Keep it rural," according to historian Willys I. Peck. Today the city serves as a bedroom community for upper-middle class Silicon Valley tech workers.
