The Pratas Triangulation Bench Mark
　　The army established this spot as the triangulation point for Pratas Island in December 1991. There are words on each side of the base of the triangulation point stone tablet. It reads "The Pratas Triangulation Point" on the front, and "Longitude: 116 degrees 43 minutes 42.5601 seconds east, Latitude: 20 degrees 42 minutes 6.2415 seconds north, Height: 2.4875 meters." The words "Defend the South China Sea," written by the commander Lo Ben Li, were also engraved on the stone tablet. In addition to making it more convenient to survey and draw navigational maps, and to construct and develop facilities on the island, the establishment of the triangulation point is also the basis of our sovereign rights.
