Quito, formally San Francisco de Quito is the capital and the largest city of Ecuador. At an elevation of 2,850 meters (9,350 ft) above sea level, it is the second-highest official capital city in the world, after La Paz, and the one which is closest to the equator. Quito has a tropical highland climate. Because of its elevation and its proximity to the equator, Quito has a fairly constant cool climate. The average temperature at noon is 18.7 °C (65.7 °F) with a normal night-time low of 9.3 °C (48.7 °F) The annual average temperature is 14 °C (57 °F). The city experiences only two seasons: dry and wet. The dry season, June through September (4 months) is referred to as summer; the wet season, October through May (8 months) is referred to as winter. Annual precipitation, depending on location, is approximately 1,000 mm (39 in).

It is located on the eastern slopes of Pichincha, an active stratovolcano in the Andes Mountains. With a population of 2.800.000 (in 2022), Quito is the most populous city in Ecuador. It is also the capital of the Pichincha province and the seat of the Metropolitan District of Quito.

Due to its geographical location and elevation, Quito receives a great amount of solar radiation, being one of the locations in the planet that receives the most.

The historic center of Quito has one of the largest, least-altered and best-preserved historic centers in the Americas. Quito and Kraków, Poland, were among the first World Cultural Heritage Sites declared by UNESCO, in 1978. The central square of Quito is located about 25 kilometres (16 mi) south of the equator; the city itself extends to within about 1 kilometre (0.62 mi) of zero latitude. A monument and museum marking the general location of the equator is known locally as la mitad del mundo (the middle of the world), to avoid confusion, as the word ecuador is Spanish for equator.

If you want more information about Quito, please visit this page:

On Wednesday August 2nd you will have the opportunity to visit Quito historic center or Quito Middle of the World in a guided tour that will take approximately 4 hours. Following is a description of both tours so you can have an idea of the program.

You can sign up and pay this activity during the first two days of the conference. There will be an information booth at the venue


Quito, a world Cultural Heritage Site (Half day excursion)

Quito´s Historical Center, the largest and best preserved in Latin America, displays on its centuries old narrow streets, plazas, churches, monasteries and monuments a superb fusion of cultures and artistic styles which fascinates visitors and represents an unparalleled historic jewel.

Ecuador’s capital, Quito, founded in 1534, sits high in the Andes at an altitude of 2.850m. Quito is a monumental city, built over the ruins of the Inca’s northern imperial seat and a fabulous example of colonial architecture and art. Quito’s center is rich with 16th and 17th century churches and other buildings, which blend traces of European, and Indigenous styles. For these reasons and the outstanding preservation of its rich legacy, UNESCO declared the entire center of Quito a World Cultural Heritage site in 1978. It was the first city in the world to receive this qualification. Surrounded by imposing mountains and volcanoes and an enviable scenery all around, Quito is just minutes away from the Line, which marks our planet’s Latitude 0.0’0’’, the Equator.

This half-day sightseeing excursion offers the best of Quito with its rich cultural legacy, ornate facades, and dazzling gilt altars. The visit may include the Independence Square, The Archbishop’s Palace, The Metropolitan Cathedral, and:

San Francisco which is city`s most ancient large cathedral Its construction started in 1535, just one year after the city’s Spanish foundation, and it was concluded in the early 1600’s. Dominating the eastern flank of the historic namesake Square, the church of San Francisco presides majestically over the square. Inside the view is stunning: gold-panned columns and altars, painted walls and ceilings, the impressive central dome illuminated by the equatorial sun. Most remarkable feature of this church is the fascinating blend of cultures and art styles, between the European and the native indigenous peoples. Here the Christian symbols mix astonishingly yet in harmony with gold-pan Sun Gods and other symbols of the Indian’s own religious beliefs and Cosmo vision.

La Compañia de Jesús, built in 1635 and finished in 1722, is, outside and inside, a masterpiece of baroque art, one of the most beautiful and startling churches in the world. Its external façade is carved with infinite detail on pure granite stones brought from Mt. Pichincha. Inside, the view is awesome: the entire church, its panels, columns, altars, pulpit, ceilings and especially its main altar glitter and sparkle with tons of gold pan, a truly unique sight. Along its walls and altars, remarkable paintings and religious sculptures are found, created by some of the colony’s most celebrated indigenous artists, guided by the hands of Spanish, Flemish and Italian friars


(Half day excursion)- 4 hours

A short drive north of the city will lead you to our planet’s Latitude 0 0’ 0’’. This is the place where you can idly stand with one foot on the northern hemisphere and the other one on the southern hemisphere…a unique experience….

The visit may include the giant monument, which marks the Middle of the World, and its surrounding complex, where visitors can learn about the 18th century French Geodesic expedition, one of the first executed under the modern scientific principles, which main´s purpose was to measure the roundness of the Earth.

Nearby is the Intiñan museum known as well as “The trek of Sun” where you will be guided through the wonderful world of the Andean Cosmo vision (view of the nature of the cosmos), Culture and Traditions. Mixed with didactic games where the physic laws show us the unique events that happen at the middle of the world.

Pre-conference Galapagos tour

San Cristobal (Galapagos) Pre-Conference Trip

USFQ has a campus in the Galapagos Island of San Cristobal and is happy to invite you to visit.

While on the island, we will give you a tour of USFQ San Cristobal Campus and Science Center on July 26th, where you can contact our researchers and see their work. Further details will be provided as the date approaches.

There are several airlines that travel to San Cristobal Island, from Quito and/or Guayaquil: Latam, Avianca and Equair.

We suggest you travel to San Cristobal on July 26th, and fly back to Quito on July 29th, but you can also plan for a longer stay in the island, arriving sooner.

July is a busy month in the Galapagos, therefore we recommend you make your flight and hotel reservations as soon as possible.

If you wish to be part of the ISSOL/IAU group we are helping to get together to visit the island, please contact Ms. Lorena Vega at:

For accommodations, we have pre-reserved rooms on San Cristobal at the Hotel Miconia:

which is a nice and very well-located hotel. We have arranged for special rates for the conference participants. For hotel reservations you can contact Kathy at: Cel: (+593) 986 - 936 - 975

Please mention you are part of the Origins 2023 group in your communication. Ms. Vega and Kathy will help you with the confirmations and payments that are needed in advance. They can also help you booking specific side-tours you might want to do while there.

We calculate that the tour could cost between $1300 to $2000 per person for the three nights, including flight, hotel, meals and island entrance fees. Besides, in the island you can take guided tours to different sights and activities that will be charged directly.

Hope you have a great stay!

Travel support

Limited travel support is available for younger researchers in need. Preference will be given to Students and Early Carrier Scientist (up to and including PhD+3).
