According to Roadside America there is a plaque at the base of the world's tallest cross, which is 208 feet high. "The Great Cross" was erected in 1966. It's built of 70 tons of stainless steel plates, packed with concrete in its lower third to prevent toppling by hurricanes. It's part of the Shrine of Our Lady of La Leche, and its height was designed so that everyone near St. Augustine could see it, and be reminded "of the religious beginning of our nation," according to the plaque.
It is not the only cross that appears in the
St. Augustine skyline. Check out the others:
