Today, Santa Teresa is largely a residential area, but also home to numerous Silicon Valley tech campuses.
Santa Teresa is the southernmost urban district of San Jose, bordering the largely protected Coyote Valley to its south.
Santa Teresa was founded in 1834 as Rancho Santa Teresa, a rancho grant given by Governor José Figueroa to Don José Joaquín Bernal, a retired soldier who came to Alta California as part of the De Anza Expedition in 1776.
The Treaty of Santa Teresa (Spanish: Tratado de Santa Teresa) was signed at the rancho in 1844, temporarily ending the hostilities between Governor Manuel Micheltorena and the revolters led by former Governor Juan Bautista Alvarado.
Tulare Hill serves as the barrier between the southern tip of Santa Teresa and Coyote Valley.
