The Castle of Heatherfield

Have you ever noticed that there's a castle on the map of Heatherfield?
Above is the Map of 12 portals from the W.i.t.c.h. comics but the castle can be soon on another map of the city, one where the homes of the 5 girls are marked on.

I was really surprised when I looked at the map of 12 Portals and suddenly there was this huge castle!!! Why did they never use this in the comics, I wonder? I'm a huge fan of castles and when you're in the genre of magic and mystery and witches and princesses and the likes... what could be better than an ancient castle right there... in HEATHERFIELD?!  Seriously!

Have you ever spotted this? What do you think could happen there? A school trip with the history teacher? A new owner of the castle who has a mysteriously dark aura to himself? A ball or a strange happening?
