The Old City Gates are a striking site toward the north end of St. George Street. The Old City Gates were at one time the only entrance into St. Augustine. The two ancient columns made of stone were built in 1808 as a line of defense for the city. Visiting the Oldest City in the United States would not be complete without taking a moment to see the Old City Gates. They are a symbol of the turbulent times faced by the original American colonists and a truly memorable landmark.
