Man it took me about one, one and a half month to get Castel de Monte with no diamonds. Lucky for me I got 3 really fast BP's from just polishing, then got about 4 new from donating and finally got two new with trading. Its only level 1 right now though.
I'm thinking going for Deal Castle next or Hagia Sophia as the happiness bonus is rather good.
