About San Diego
San Diego, about 13 miles from the border of Mexico, is the second-largest city in California and the eighth-largest in the nation. Founded by Spanish colonists in 1769 with the Presidio & the San Diego Mission, the city later became Mexico territory until 1850 when it officially became part of the United States after the Mexican-American War. San Diego is today a center of research in biotechnology and in military and defense-related activities. San Diego first city-center was the “Old Town” district, later replaced by the “new town”, which is present-day waterfront Downtown. San Diego is popular for its mild year-round climate, natural deep-water harbor and extensive pristine beaches.
