San Mateo, CA was incorporated in the year 1864. Originally part of two large Rancheros, the city now has a population of approximately 100,000 residents, making it one of the larger suburbs in the San Francisco Bay area.
The first official business enterprise was started in 1849, a stagecoach stop built in what is now an abandoned mission. The train soon followed, linking San Mateo to San Francisco in 1863, and the area was originally built up from wealthy San Franciscans looking for an area with a mild climate to build homes for summer use or as a permanent residence. San Mateo fit the bill.
