There are countless points where lines of latitude and longitude intersect, but very few are marked, let alone made accessible. Just outside the city of Hangzhou, in a quiet patch of Fuyang District, lies one of the rare geodetic “perfect crossings”: the exact point where 30°0’0” N meets 120°0’0” E.
Marked by an official concrete pillar inscribed 国家测量标志 (“National Survey Mark”) and a geodetic triangle labeled by the Zhejiang Bureau of Surveying and Mapping, this site quietly celebrates the human drive to map and measure the world. Despite being built in 1995, it remained mostly unvisited and undocumented online for years. No tourist signs, no plaques—just the sheer precision of GPS and the satisfaction of reaching a mathematically pristine spot on Earth.
Visitors can verify the coordinates on their GPS or phone—some even place their device directly atop the survey marker to match the numbers exactly. For lovers of geography, maps, and the oddly satisfying, this is a quiet yet thrilling place to stand.
