Usa first city history

The history of the "first" city in the United States depends on how you define the term—whether you mean the oldest continuously inhabited European settlement or the first major city of the British colonies.

Here is the breakdown of the most significant "first" cities in the USA.

1. St. Augustine, Florida (The Oldest)
Founded on September 8, 1565, by Spanish explorer Pedro Menéndez de Avilés, St. Augustine is the oldest continuously inhabited European-established settlement in the contiguous United States.

Spanish Roots: It served as the capital of Spanish Florida for over 200 years.

Strategic Defense: The Spanish built the Castillo de San Marcos, a massive masonry fort, to protect their treasure fleets from pirates and the British.

A Diverse Start: Long before the Pilgrims landed, St. Augustine was a melting pot of Spanish soldiers, African slaves, and indigenous Timucua people.

2. Jamestown, Virginia (The First English)
