The main attraction of this monument is at the time of culmination, when the sun was right on the equator. At that time the shadow of the monument 'disappeared' for a few seconds, even if exposed to sunlight. The event of sun culmination occur twice a year, between March 21-23 and September 21-23.
Historical records say that on March 31, 1928 an international expedition led by a Dutch geographers come to Pontianak to determine the point/milestone of the equator line. In 1928, the first monument of the arrow-shaped pillar successfully built. Milestone was later refined in 1930, in the form of milestone with circle and arrow. In 1938 the architect Silaban make improvements and build a new monument. (The original monument can be seen inside this monument).
In 1990, the monument was renovated again with the dome construction to protect the original monument and the making of a duplicate of original monument with 5 times larger size than the original monument.
