Using simple tools and methods, an unnamed Dutch geographer and explorer spearheaded a mission to find a city on the Equator. Eventually, in 1928, he found this city by the longest river in the Indonesian archipelago that was the sole urban setting right on the line of the Equator. He immediately marked the spot on the river bank of Kapuas Kecil (small Kapuas) with a simple pole and an arrow. Only 70 years later, when the monument had passed many renovations and reconstructions, that Indonesia's Agency for Applied Technology made precise studies, made corrections to the exact spot of the Equator using geographic positioning system. Although the difference proved to be quite considerable, yet admiration to the original team of explorers remains and will never be forgotten.
