The Shipwreck Hall in the Port Elizabeth Museum at Bayworld has some excellent information on shipwrecks around Port Elizabeth. The displays contain a lot of artifacts salvaged from wrecks like the Sacramento, Amsterdam and Doddington. One of the items that form the centerpiece display is a cannon salvaged from the wreck site of the Portuguese galleon Sacramento near Schoenmakerskop in the 1970’s. The Sacramento ran aground in a storm on this coastline in 1647 with 72 survivors making it to land before staring their 1400km walk to present day Maputo.
