Pedro Menéndez de Avilés sights land near St. Augustine, Florida and founds the oldest continuously occupied European-established city in the continental United States.

Pedro Menéndez de Avilés was a Spanish admiral, explorer and conquistador from Avilés, in Asturias, Spain. He is notable for planning the first regular trans-oceanic convoys, which became known as the Spanish treasure fleet, and for founding St. Augustine, Florida, in 1565. This was the first successful European settlement in La Florida and the most significant city in the region for nearly three centuries.

St. Augustine is a city in and the county seat of St. Johns County, Florida, United States. Located 40 miles (64 km) south of downtown Jacksonville, the city is on the Atlantic coast of northeastern Florida. Founded in 1565 by Spanish settlers, it is the oldest continuously inhabited European-established settlement in what is now the contiguous United States.

The contiguous United States, also known as the U.S. mainland, officially referred to as the conterminous United States, consists of the 48 adjoining U.S. states and the District of Columbia of the United States in central North America. The term excludes the only two non-contiguous states and the last two to be admitted to the Union, which are Alaska and Hawaii, and all other offshore insular areas, such as the U.S. territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands. The colloquial term Lower 48 is also used, especially in relation to Alaska. The term The Mainland is used in Hawaii. The related but distinct term continental United States includes Alaska, which is also on North America, but separated from the 48 states by British Columbia in Canada, but excludes Hawaii and all the insular areas in the Caribbean and the Pacific.
