The tower of the eternal night is an emblematic place. It's status in the form of dragons advancing in the void was intended to guide the lost of the valley. A magic spell of eternal light was cast on a candle located in the mouth of the dragon. At the time it saved the lives of so many walkers/travelers that they never stopped counting. Now nature has taken over and you can see ivy hanging down the dragon's body or a tree growing from its head. The ruin being classified as a world heritage site and considered as dangerous, it is impossible to climb the mountain to visit it. However, it is possible to climb the nearby peak to take a picture of it. From 11pm onwards you can see the dragon taking over the sun as it sets and its mouth lights up.
