San Diego has one of the best natural harbors on the West Coast. The city is even named for a Spanish ship, the San Diego, which sailed into the harbor on Saint Diego's name day, sixty years after the Spanish had claimed the area.
Slowly, San Diego grew into a developed port and a village sprang up around the primary industry, fishing. In the mid nineteenth century, the Mexican War drove the citizens from the town and the port was commandeered by the navy. Still today, the port primarily serves the U. S. Navy, as home to the 3rd Fleet.
After the war, a developer, by the name of Horton, decided that the land near the abandoned adobes had possibility. He bought several acres of land for twenty-five cents an acre and sold them to adventure-seeking males looking for a piece of California. Within two years, the modern city of San Diego, founded three miles from original site, went from 0 population to 2000.
Today, San Diego has grown to encompass both the original site and the one founded by Horton. The old section survives as Old Town, the navy is in port, and fishing boats fill the bay, reminders of both where the city has been, and where it is going.
