The monument is located at 23.45 degrees north latitude, which is the precise calculated position of the Tropic of Cancer.
This location is one of the few places in the world where one can physically stand on the Tropic of Cancer line while visiting a dedicated science center.
The center has undergone six distinct design iterations since the first monument was erected in 1908 during the Japanese colonial era.
The center includes a solar telescope that allows for regulated observation of the sun's surface features.
The park's design incorporates 'Time Path' walkways that demonstrate the relationship between the Earth's orbit and solar position.
The Tropic of Cancer Solar Exploration Center in Chiayi is located exactly on the 23.5-degree north latitude line, marking the geographical boundary of the northern tropics. It serves as an educational park dedicated to solar science, astronomy, and the study of the sun's position relative to Earth. The current site features the sixth iteration of the monument, which was constructed to replace older versions damaged by historical earthquakes. The grounds include an interactive science museum, outdoor solar-themed art installations, and educational displays explaining the significance of the Tropic of Cancer. Visitors can stand on the physical line demarcating the transition between the tropical and subtropical climate zones. The architecture features modern, futuristic design elements designed to house astronomical instruments and solar-observation equipment. It functions as a public park with walking paths that integrate geographical education with recreational space.

Bring a hat and sunscreen as the site is almost entirely exposed to direct sunlight with minimal natural shade.
Visit the interactive exhibits inside the building to better understand the scientific significance of the markers outside.
Check the weather forecast for clear skies to ensure the best experience with the outdoor solar observation points.
Do not skip the indoor displays; many visitors focus only on the outdoor monument, missing the core scientific context provided inside.
The indoor exhibition area is typically closed on Mondays.
