Tropic of Cancer Marker at Jingpu Introduction
The Tropic of Cancer is located at 23.5 degrees North latitude, marking the northernmost point of the sun's direct overhead rays and serving as the boundary between the subtropical and tropical zones. The marker for the Tropic of Cancer in Jingpu is situated at kilometer 69 on Taiwan Route 11. Every summer solstice, the sun rises in the east and sets in the west along the white tower's body. Therefore, a narrow slit is designed on the coordinate tower to observe this phenomenon, and at noon on the summer solstice, sunlight will perfectly illuminate the slit, allowing visitors next to the tower to experience the remarkable phenomenon of having no shadow under the sun.
