The Old Town area remained the heart of the city of San Diego until the 1860s, when a newcomer to San Diego named Alonzo Horton began to promote development at the site of present-day Downtown San Diego. Residents and businesses quickly abandoned "Old Town" for Horton's "New Town" because of New Town's proximity to shipping. In 1871 government records were moved from Old Town to a new county courthouse in New Town, and Downtown permanently eclipsed Old Town as the focal point of San Diego.
