Celestial Well is an iconic marine erosion wonder in Pingtan. The naturally formed giant marine erosion shaft is dozens of meters deep, with steep cliffs on three sides, and caves at the bottom connecting to the open sea. Waves rush in and thunder against the rocks, forming the magnificent "Dragon Palace Listening to Waves". Carved by thousands of years of wind and waves, it combines precipitousness, grandeur and delicacy. It is a must-visit site to explore natural secrets and experience the charm of marine geology, showing the geological wonders on the coast of the East China Sea.
