Mystery of red balls on castle gate

HI Guys,i was wondering if anyone could tell me why there are red balls on the castle gate?

Is there any history or mystery?


i think its just for decorate and nothing more. I don’t think its related to Doom Gate or anything.

The TWO EYES of Sauron!!

Flare must be fan of Lord of the Ring

Well, who isn’t though :wink:
