Strange building

Hey can anyone explain to me what the building right to the warehouse on this picture from haypi's website is???

It is not on my haypi iphone version...

This is a new addition to the game that will be included in the 3.0 update. This version of Haypi has not yet been released, and so it should not show up in your current game. :)

Ahh okey thanks a lot
Was wondering if it was some secret magic building

It's called the "Battle Field," so I assume that'll be the place where alliance wars are held. You can find more details about the upcoming update here.
