History of Castro Valley

Long ago, before Europeans arrived, the area was home to the Chocheño people. They were a group of Ohlone Native Americans.
In 1797, Europeans built Mission San Jose nearby. The land that is now Castro Valley was part of a large area called New Spain. This was a colony of Spain in what was then Alta California.
In 1840, Guillermo Castro received a huge land grant called Rancho San Lorenzo. It was about 28,000 acres. This land included what are now Hayward, San Lorenzo, and Castro Valley. Castro had to sell parts of his land because of gambling debts. The last part was sold in 1864.
A man named Faxon Atherton bought the land. He then started selling it in smaller pieces. In 1866, the Redwood school was built. This was the first public school in the area. Many Portuguese families moved to the canyons nearby. They farmed large amounts of land. In the 1870s, Lake Chabot, a reservoir and park, was built.
During the 1940s and 1950s, Castro Valley was known for its chicken farms. Later, it became a "bedroom community." This means many people live there but travel to other towns for work.
