The Colossus Of Rhodes
The Colossus of Rhodes was a statue built to commemorate the successful defense of Rhodes city against a year-long siege by Demetrius Poliocretes. Standing approximately 108 feet tall, the tallest ancient statue is considered to be one of the original Seven Wonders of the Ancient World. However, it didn't stand for long: build by Chares of Lindos in 280BC, the colossus lasted only 54 years and collapsed during the earthquake of 226 BC. In accordance with a certain oracle, the Rhodians did not build it again. In the 21st century, there were proposals to build a new Colossus at Rhodes Harbor, and in 2015, some architects proposed a promising project, though some scholars criticize the location, claiming that it couldn't have been the original spot.
no one could know how this fantasy building would have looked if it was real, like saurons tower ;)
