The “Nations Oldest City” is what St. Augustine is often referred to. It was founded in 1565 by Spanish explorers. It is the oldest continuously inhabited European established settlement in the mainland United States. San Juan, Puerto Rico is the oldest settlement, founded in 1521. Eventually, Spain ceded Florida to the United States in 1819. At the time, St. Augustine was the capital of the Florida Territory but it was moved to Tallahassee in 1824.
