For two centuries St. Augustine was the northern guardian of Spanish Florida. After an English raid burned the wooden town, Spain answered with stone: between 1672 and 1695 they built the Castillo de San Marcos out of coquina — a soft shell-limestone quarried from Anastasia Island across the bay, packed so full of crushed seashell that it absorbed cannonballs rather than shattering. The fort is the oldest masonry fortification in the continental US, and across two major British sieges — Governor Moore in 1702, who burned the city around it, and General Oglethorpe in 1740 — it was never taken by force. Spain, Britain, and the United States all flew flags over it in turn, every change of hands by treaty rather than conquest. In the 1880s, the railroad magnate Henry Flagler arrived and remade the old garrison town into a Gilded-Age winter resort, raising the Spanish Renaissance Hotel Ponce de Leon in 1888 and the Hotel Alcazar nearby — buildings that anchor the old town's skyline to this day.
Over centuries the city changed hands between Spain, Britain, and the United States, each leaving its mark on the architecture, the street grid, and the place names. By the late nineteenth century, Henry Flagler's railroad brought northern winter visitors by the trainload, and the old garrison town picked up Spanish Renaissance hotels, a Mediterranean Revival bridge, and the look of a resort. The Castillo became a national monument in 1924. In 1965, on its four-hundredth anniversary, St. Augustine paused to take stock of how much had survived intact — the fort, the street grid, the Cathedral, the lanes — and the modern preservation era began. Today the old quarter is a national historic landmark and a year-round destination, anchored by the Castillo, the lighthouse on Anastasia, and the Bridge of Lions.
