pirate fleet and in 1684 missions along what is now the Georgia coast were attacked by Native American allies of the English. The mission of San Buenaventura was ordered to move south and merge with the mission of San Juan del Puerto on the St. Johns River. Before the mission could be moved, pirates returned to the area in the second half of 1684. On hearing of the presence of the pirates, Lorenzo de Santiago, chief of San Buenaventura, moved the people of his village, along with most of their property and stored maize, to the mainland. When the pirates landed at San Buenaventura, they found only ten men under a sub-chief who had been left to guard the village.

It has been preserved in the 20th century and identified as a national historic site largely by the efforts of Margaret Davis Cates, a local resident who contributed much to historic preservation. She helped raise more than $100,000 in 1941 to buy the site of the fort and conduct stabilization and some preservation. It was designated as a National Monument in 1947. Wesley brothers In the 1730s St. Simons served as a sometime home to John Wesley, the young minister of the colony at Savannah. He later returned to England, where in 1738 he founded the evangelical movement of Methodism within the Anglican Church.
