The Conservation Research Laboratory (CRL) at Texas A&M University is restoring 25 cannons from the Castillo de San Marcos, the oldest masonry fort built in the continental United States. Now a national monument in St. Augustine, Florida, the fort is home to cannons from periods ranging from 1690 to 1846. The first 14 cannons arrived at the lab June 11.
“The last time these cannons were worked on was in the 1990s,” said Chris Dostal, a research assistant for the CRL. “They’re on the coast of Florida, and the salt could turn them into piles of rubble if we don’t keep them from corroding.”
