How do you get 4 pieces door in kingdom hearts 1?

Answer 1

If your talking about the door in Hallow Bastion then on the second floor there are statues, one asks you to move it, another smash it, and there are candles near them. You need to light them, plus there is a stone with a thunder sign on it (use thunder). But if your talking about the one in End of the World, then all you need is to fight the Heartless.
