Antonio López Wreck
Puerto Rico · 3–10 m
The SS Antonio López, an 1882 Scottish-built Spanish Compañía Trasatlántica steamer, was shelled by the USS Yosemite while running the US blockade and ran aground on Angelina barrier reef off Dorado on 28 June 1898; she was later burned by USS New Orleans and sank in place. The wreck — the only known Spanish shipwreck in US waters from the Spanish-American War — lies substantially intact in about 30 ft (9-10 m) of water roughly a mile offshore, with boilers, machinery, masts, anchors and extensive hull remains easy to identify. Designated a National Historic Landmark in 1997, it is a shallow boat dive best attempted on calm summer days, as the north coast is exposed to Atlantic swell.
