The San Diego Viejo Plaza site is California Historical Landmark No. 63, listed on December 5, 1932. The plaza (town square) was the center of Pueblo de San Diego founded in 1835 in Alta California. ^{[2] [3] [4]}

History

The major buildings and houses of Pueblo of San Diego were built around the town square. ^[5] Pueblo of San Diego was the first permanent Spanish settlement in California. In 1769, Father Junípero Serra's mission and Gaspar de Portolá's Presidio of San Diego were built over looking the Pueblo of San Diego. Ships coming to Pueblo of San Diego sailed into San Diego Bay. The first houses (casas) at the plaza were built in about 1821. ^{[6] [7]} In 1827 over 30 adobe homes had been built around the San Diego central Plaza, many the homes were for retired Spanish Empire veterans. The only large house in the plaza was La Casa de Juan Bandini. From 1770 to 1822 Pueblo of San Diego was ruled by a commandant from the Presidio of San Diego under the New Spain. In 1822 the First Mexican Empire took control of the government in Pueblo of San Diego. The Mexican secularization act of 1833 opened up mission land for citizens. In 1835 San Diego had a population of 500 and the First Mexican Republic declared San Diego an official pueblo, city status, and could have it own elected mayor ( alcalde), not under military rule of the Presidio. Pueblo status was granted after a petition was sent to Governor José Figueroa and endorsed by Commandant Santiago Arguello. In 1838 San Diego lost its Pueblo status because of the declining population. ^[8] The United States acquired Alta California and San Diego through the Mexican–American War and the Treaty of Guadalupe Hidalgo. ^[9] On July 29, 1846, at 4 p.m. the first Flag of the United States was raised in Plaza San Diego Viejo by Lt. Stephen C. Rowan, a United States Navy commander of US sailors and US marines. Stephen C. Rowan arrived at US sloop-of-war USS Cyan built in 1837. After the war the United States renamed the plaza, Washington Square. ^{[10] [11]}

Pueblo of San Diego Plaza was an inland town as such in 1850, new building started at San Diego Bay, The US Army built New San Diego Barracks in 1850 and 1851, a supply depot and wharf. The depot was built in what was called at the time New San Diego, on San Diego Bay, south of Pueblo de San Diego. ^[12] New San Diego was built into a town by William Heath Davis in the early 1850s. ^{[13] [14]}

By 1890 many of the houses and buildings became run down. The plaza had been neglected and many of the original homes and buildings were demolished. In the 1920s and 1930s preservation works started to save the remaining buildings and homes. The Works Progress Administration did restoration in the 1930s of a few remaining buildings, including the Casa de Estudillo. The State of California designated Old Town San Diego as a California State Historic Park in 1968 and more preservation and reconstruction work was done. With the new California Historic designation, the title San Diego Viejo Plaza and Plaza de Las Armas came back in use. ^{[2] [15]}

Early mayors, called Alcalde, of Pueblo de San Diego, included: Juan María Osuna, Santiago Argüello, José Antonio Estudillo, Rosario E. Aguilar, Jesús Moreno, and José María Alvarado. The city of San Diego Incorporated on March 27, 1850. ^[16] The State of California was admitted to the Union on September 9, 1850. ^{[17] [18]}
