The monument was constructed as part of a project to celebrate the new millennium in 2000.
The architectural design by Eleanor Burciaga consists of two pillars that do not touch, framing the solar path.
The site sits at an elevation of approximately 30 meters above sea level.
It is one of the few places in the world where the Tropic of Capricorn can be easily visited by vehicle on a paved highway.
The structure acts as a large-scale sun dial during specific times of the year.
The Hito Tropic of Capricorn monument marks the exact geographic line of the Tropic of Capricorn at 23°26'16" S latitude in the Atacama Desert. The site features a 13-meter-high concrete arch structure representing the solar meridian. It serves as a symbolic gateway between the temperate zone and the torrid zone of the Southern Hemisphere. Situated along Ruta 1, the monument commemorates the astronomical phenomenon where the sun reaches its zenith during the summer solstice. The surrounding landscape is characterized by arid coastal desert terrain typical of the Antofagasta region. It remains a popular point for travelers navigating the coastal road toward the north of Chile.
