After a brief stop at Jamaica, Columbus sailed to Central America, arriving at Guanaja (Isla de Pinos) in the Bay Islands off the coast of Honduras on 30 July. Here Bartolomeo found native merchants and a large canoe, which was described as being long as a galley and filled with cargo.
Christopher Columbus claimed Jamaica for Spain after landing there in 1494. Columbus' probable landing point was Dry Harbour, now called Discovery Bay. St. Ann's Bay was the Saint Gloria of Columbus who first sighted Jamaica at this point.
