St. Augustine is the oldest continuously settled city in the United States located in northeastern Florida.

In 1564 France established Fort Caroline near the mouth of the St. Johns River, about 35 miles (55 km) north. A year later, in order to maintain Spanish sovereignty over Florida, Pedro Menéndez de Avilés destroyed the French colony and founded the city, which he named for St. Augustine, Except for the 20 years (1763–83) that Florida belonged to England, throughout the following 256 years it was the main northern outpost of the Spanish colonial empire.

Since 1821 the city has been a part of the United States. A remaining symbol of former Spanish power is the massive Castillo de San Marcos, built in 1672–95 near the southern tip of the peninsula; the oldest masonry fort standing in the United States, it is now a national monument.
