Divine Lighthouse

No one is sure which dynasty built this lighthouse. It has been here as long as anyone can remember. People ventured inside from time to time, but almost everyone gave up before reaching the top. "Those stairs are endless!" they always complained, yet the tower appears quite ordinary and not that tall from the outside. When two youths finally completed the climb, they came back mentally scarred. From that day forth, they muttered endlessly to themselves about seeing heaven itself.
