 A geological feature of historical importance is the "Spanish Rock", (also known as "Portuguese Rock") a rocky cliff overlooking the ocean with inscriptions of the year 1543 AD and indistinct other writings.Inscriptions have been interpreted as along with other markings "RP" (abbreviated version of Rex Portugaline, King of Portugal) and a cross denoting the Portuguese Order of Christ.This rock piece has been taken out and replaced by a bronze plaque.
