Santa Clara, CA is located in Santa Clara County and founded in 1777 with the establishment of the 8th out of 21 missions in CA. The locale was originally used to grow crops to support the mission as the soil and climate were ideal.

In 1846 for the first time, the American flag was raised signifying the transfer from Mexico to the US. Incorporated as a city in 1852, the area saw agriculture as its most common industry. In 1905, the first high altitude flights were made over Santa Clara in gliders designed by John Montgomery.

It also is the location of the oldest institution of higher learning, the Santa Clara University now housed on the grounds of the old mission. The home of the National Football League’s San Francisco 49’ers plays home games in Levi’s Stadium.

The semiconductor industry arrived in 1960, changing the face of Santa Clara from agriculture to the high tech industry. The area is now part of Silicon Valley and home to some of the greatest hi-tech industries including Intel.
