In 1926/7 Victor Peers and his son Bertram excavated the cave now known as Schildersgat, which later became known as Peers Cave. They found many stone tools and the remains of nine people, one of whom became famous as Fish Hoek Man. The skull has the largest brain area of any skull of its age found up until that time, and has been dated at 12,000 years old. In January 1941 Peers Cave was declared a National Monument. The location affords beautiful views across the peninsula to both oceans from across the valley and a peep into stone-age history.
