Half of the World, Quito is a part of the Quito city which was constructed in commemoration of the First Geodesic Mission that came to Ecuador in the year 1736. This Geodesic Mission was led by people such as Pedro Bouger, Luis Godin and Carlos Maria de la Condamine of France and Jorge Juan and Antonio de Ulloa of Spain and Ecuadors' Pedro Vicente Maldonado. Their mission was to prove the roundness of Earth. The study for the mission lasted for nine years and after the end of the mission they started calling the territory of Quito as 'Territories of Ecuador'.

In the year 1802, another mission came to Ecuador under the supervision of Charles Perrier. The purpose was to corroborate the data collected by the first group of investigators. In the year 1836, the Ecuadorian geographer Luis Tufiño located all the landmarks that were identified by the First Mission. An obelisk of 10 meters was erected in San Antonio de Pichincha which was later transferred to Calacalí.
