First School in Mira Loma

In 1888 A.J. Stalder donated land for the first school in what is known today as Mira Loma. Lumber and labor were donated by local families to build the school in 1892. It was known as the Pleasant Valley school. Just a year later the County of Riverside was formed from portions of San Diego and San Bernardino. A school in the Winchester area was also known as Pleasant Valley so our Mira Loma school changed its name to Union, which was the name of the election district for that area. The school was located where Etiwanda intersects the 60 freeway today. This little school served the children of the area until a new school was built in 1915.
