Prior to occupation by the Spanish, the site of the Presidio was home to the
Kumeyaay people (called the
Diegueños by the Spaniards). , donated to the city by Mexican President
Gustavo Díaz Ordaz in 1970, honors the 200th anniversary of the founding of Presidio of San Diego. The first Europeans to explore
San Diego Bay and its environs were members of the maritime expedition led by
Juan Rodríguez Cabrillo in 1542.
Sebastián Vizcaíno visited again in 1602, but no settlement was made until the fort was begun in May 1769. On July 16, 1769,
Mission San Diego de Alcalá was established by
Junípero Serra on Presidio Hill. The presidio had a commanding view of San Diego Bay and the Pacific Ocean, allowing the Spanish to see potential intruders. Less than a month after the mission was established, a Kumeyaay uprising occurred; four Spaniards were wounded and a boy was killed. After the attack, the Spaniards built a stockade which was finished in March 1770. It included two bronze cannons: one pointed to the bay, the other to the nearby Indian village. In 1773 and 1774,
adobe structures were built to replace the temporary wood and brush huts. Later in 1774, the mission was moved a few miles up Mission Valley to separate the Kumeyaay from the influence of the presidial garrison. By 1783, there were 54 troops stationed at the presidio. With
Mexican independence in 1821, the presidio came under Mexican control, and was officially relinquished by the Spanish on April 20, 1822. From 1825–1829, it served as the Mexican governor's residence. The presidio was abandoned by 1835 and fell to ruins, because settlers preferred to live in the more accessible town—present-day
Old Town San Diego State Historic Park—which developed at the foot of Presidio Hill. ==Preservation==
