As the first European settlement in Southern California, Old Town began to develop in the 1820s. However, its true beginnings took place on a nearby hillside in 1769 with the establishment of a Spanish military outpost and the first of California’s missions, San Diego de Alcalá. In 1774 the hilltop was declared a presidio reál, a fortress built by the Spanish empire, and the mission was relocated along the San Diego River. Over time, settlers moved down from the presidio to establish Old Town. A central plaza was laid out, surrounded by adobe and, later, wooden structures. San Diego became an incorporated U.S. city in 1850, with Old Town as its center. In the 1860s, however, the advent of Alonzo Horton’s New Town to the southeast caused Old Town to wither. Efforts to preserve the area began early in the 20th century, and Old Town became a state historic park in 1968.

Today Old Town is a lively celebration of history and culture. The Old Town San Diego State Historic Park re-creates life during the early settlement, while San Diego Avenue buzzes with art galleries, gift shops, festive restaurants, and open-air stands selling inexpensive Mexican handicrafts.
