Pengilih Point / Concrete mounting block / #16 on the layout map

Concrete block dimensions :

Top: 48" X 53"
Base: 72" X 72"
Height: 3ft
On the top of the block you can make out a silhouette of dark circular ring. This ring could have either been made by a mounting ring used by a crane to lift the block into place, or evidence of the equipment that was once installed on top of the block.
