The Ciudad Mitad del Mundo is a tract of land owned by the prefecture of the province of Pichincha, Ecuador. It is located at San Antonio parish of the canton of Quito, 26 km north of the center of Quito. The grounds contain the Monument to the Equator, which highlights the exact location of the Equator and commemorates the eighteenth century Franco-Spanish Geodesic Mission which fixed its approximate location; they also contain the Museo Etnográfico Mitad del Mundo, Ethnographic Museum Middle of the Earth, a museum about the indigenous people ethnography of Ecuador.
The 30-metre-tall monument was constructed between 1979 and 1982 by Architect and Contractor Alfredo Fabián Páez with Carlos Mancheno President of Pichincha's Province Council to replace an older, smaller monument built by the Government of Ecuador under the direction of the geographer Luis Tufiño in 1936. It is made of iron and concrete and covered with cut and polished andesite stone.
