La Placita (originally: La Placita de los Trujillos; alternate: San Salvador)[1] is a former settlement and the earliest community established in Riverside County, California, USA.[2] The town was informally established soon after 1843[3] on the Santa Ana River, across from the town of Agua Mansa.[4] La Placita and Agua Mansa were the first non-native settlements in the San Bernardino Valley.[5] Together, they were referred to as "San Salvador",[6] and were the largest settlements between New Mexico and Los Angeles in the 1840s.[7]
