The Equator is an imaginary line on the Earth's surface approximately equidistant from the North Pole and South Pole and it divides the Earth into two Hemisphere - Northern and a Southern Hemisphere.

Although major portion of the Equator lies on ocean but it mainly crosses Indonesia, Sumatra, Central Africa and South America.

In few cities around the World, Equatorial Markers/Monuments have been erected to attract tourists. I have tried to locate and placemark such monuments and these are listed below in sequential order of movement of Sun from East to West. Maximum numbers of monuments (four) are located in Ecuador - a country whose name itself means Equator. However these monuments have some controversy regarding correct location on the true Equator.
  1. Pontianak, Indonesia
  2. Bonjol, Sumatra, Indonesia
  3. Nanyuki, Kenya
  4. Siriba, Kisumu-Busia Road, Kenya
  5. Nabusanke, Masala-Kampala Road, Uganda
  6. Kikorongo, Fort Portal - Mpondwe Road, Uganda
  7. Mbandaka, DR Congo - An historical marker made by the famous Sir Henry Morton Stanley of "Dr. Livingstone, I presume?" fame. (added Oct. 1, 2009)
  8. Near Kango, Libreville-Lambaréné (N1) Road, Gabon (added Oct. 27, 2009)
  9. Islet of Rolas (Ilhéu das Rolas), Sao Tome and Principe Islands
  10. Macapá, Brazil
  11. Guachalá, Cayambe, Ecuador
  12. The "un-official" Mitad del Mundo (Middle of the Earth), San Antanio, Ecuador
  13. The "official" Mitad del Mundo (Middle of the Earth), San Antanio, Ecuador
  14. The old Equator Monument, Calacalí, Ecuador
Some of these locations were already placemarked but I have placemarked them afresh so that all the locations are covered in a single folder. I request my readers to let me know if I have missed out any monument.

Here is a Map showing the relative locations.

(Note: The monuments in Ecuador are so close that these cannot be individually identified on a map of this scale.)

The basic design of this monument is same as the one at Nabasunke, Masala-Kampala Road, Uganda (# 5).

7. Mbandaka, DR Congo

Mbandaka town was founded in 1883 by Sir Henry Morton Stanley of "Dr. Livingstone, I presume?" fame who had given it the name of "Equateur". Stanley had placed a large "Equator Stone" near the river bank south of the city to mark the point where he believed the Equator to cross the river. It remains there even today. (Source: Wikipedia)

8. Near Kango, Libreville-Lambaréné (N1) Road, Gabon

Note: The markers shown in these two images are basically same. The first one was made by AgroGabon, a Govt. owned company which was later privatised and taken over by Siat Gabon in 2004. The marker was therefore re-designed and the second image shows the new marker. However the locations of the two images in Panoramio are not matching. I have placed the GE placemarker based on the location marked by Yves Galipeau.

Credits: I am thankful to Yves Galipeau for informing me about this location and also about AgroGabon/Siat.

9. Islet of Rolas (Ilhéu das Rolas), Sao Tome and Principe

This monument in the shape of a giant sun-dial is in Guachalá, Cayambe, Ecuador. Reportedly this is the only monument in Ecuador built exactly on the equator line. It is part of Quitsato Project a non-profit project that destines its funds for the investigation of the equatorial line.

12. The "un-official" Mitad del Mundo (Middle of the Earth), San Antanio, Ecuador

Unlike other places, there are two Equatorial monuments in San Antanio. This is the unofficial one and is closer to the Equator as compared to the official one which is about 200 meters South-West of this location (see #13 below).Intiñan Site Museum is also located at this spot. Although it has staked claim for being virtually on the equator this claim is disputed by others. (Ref: http://www.therealequator.com)

It is worth noting that "The Catequilla", an ancient Inca archaeological site about 3 kilometres to East, (shown below) is believed to be on the equator itself.

The Quitsato Project using WGS 84, which is reportedly the most exact and up to date global positioning system, discovered that the peak of Mount Catequilla archaeological site was located exactly at the zero latitude ( 0º 0' 0" ).

For location see "Inca's Circle of the Middle of the Earth" post in GEC by Juandiego.

13. The "official" Mitad del Mundo (Middle of the Earth), San Antanio, Ecuador

Based on the tools available with them in 1930s, the French Academy of Sciences had decided the location of the Equator at this site. Accordingly in 1936, with the support of the French American Committee, Ecuadorean geographer Dr. Luis Tufiño built a 10-meter monument at this location.

In 1979, the old monument was moved 7 km to the west, to the town of Calacalí (see # 14) and a larger replica of the original monument was made at the site although it was and remains about 200 metres away from the Equator. This slightly mislocated monument is the official and touristy monument and is called "Mitad del Mundo" (Middle of the World).

Mitad del Mundo contains a small Museum of local culture and other attractions such as a Planetarium, an amazing miniature model of Quito, the capital of Ecuador, and restaurants. A small town surrounding the monument at the Museo Etnográfico functions as the tourist center, replicating a colonial Spanish town and is called "Ciudad Mitad del Mundo" (Middle of the World City).

14. The old Equator Monument, Calacalí, Ecuador

Image from Panoramio is by Zsolti a Béka

This monument was originally at San Antanio, about 7 kilometres to East, but in 1979 it was shifted to Calacalí, and is located near to, but not on the, true equator line. As per this webpage the Equatorial line is close to the Pileta de la Plaza de Cala Calí, about 180 metres North of the present location.

Its larger giant size replica has been built afresh on the original touristy site at San Antanio, (see # 13) and is called "Mitad del Mundo".

Edit Notes:
Dated Oct.1, 2009
I am thankful to Wacope who, vide his comments dated June 15, 2009, had given some suggestions and had also pointed out few discrepancies in my original post about the monuments in Ecuador.

While revising I luckily found an equatorial marker in Mbandaka, DR Congo which was not included in my earlier post. This marker was created by none other than Sir Henry Morton Stanley of "Dr. Livingstone, I presume?" fame. I have placemarked it now and have also included this historical marker in this collection.

Dated Oct. 27, 2009
I am thankful to Yves Galipeau for informing me about the marker on Libreville-Lambaréné (N1) Road, Gabon and also about Agrogabon/Siat. The present revision is based on the information given by Yves Galipeau.

Dated Nov. 5, 2014
I am thankful to Kelley MacTavish for pointing out a typographical error in my post. Based on his comments, the name for #5 - Nabasunke, Masala-Kampala Road, Uganda has been corrected to Nabusanke, Masala-Kampala Road, Uganda.
