The Hwangryongsa temple, a 9-story pagoda, was built in 645 AD by Silla (one of the Three Kingdoms of Korea), but was demolished in 1238 during the Mongol invasion of Korea.

Now it seems that they’re building a new 82m tall tower called Gyeongju Tower, inspired by the old temple.
It’s kind of.. weird looking, but I have to say it also looks very interesting.
