Rialto History

Rialto was incorporated as a city in 1911, but its roots trace back to well before the year 1500, which is when archaeologists believe the first Indian settlements took place. Much later, around the late 1800s, the area began to be settled by families whose primary pursuits were agriculture and ranching, with vineyards and citrus groves abundant in the region. Rialto continued to grow steadily, culminated by a huge population spike occurring between 1950-1980, when the population increased more than ten-fold. It is not completely clear how Rialto got its name. One theory is that the name was formed by a contraction of the Spanish words Rio (river) and Alto (high). Another story is that the city was named after the Rialto Bridge (a landmark of Venice, Italy). Regardless, the bridge has been retained as a community symbol known as the "Bridge of Progress."
