Shantou Tropic of Cancer marker tower

The Shantou Tropic of Cancer marker tower is a structure built at exactly 23.44 degrees north latitude, marking where the sun passes directly overhead during the summer solstice. The tower features informational displays that explain why this location holds geographic significance.

The tower was built as part of a national project to establish geographic reference points across China and advance scientific understanding. It represents an effort to help people grasp how latitude and positioning work on a global scale.

The tower serves as a gathering point where visitors learn about the sun's path and why this latitude matters to our planet. Local students and families come here to understand the science behind seasonal changes in their region.

The tower is accessible by public transportation from downtown Shantou and welcomes visitors regularly throughout the day. Information on-site helps you understand the geographic phenomenon without requiring any specialized knowledge.

On just a few days each year, when the sun passes directly overhead at this location, objects cast virtually no shadow. This visible phenomenon lets visitors directly experience how Earth's tilt affects the sun's position.
