Please read carefully:

2) Castling is prevented temporarily:
if the square on which the king stands, or the square which it must cross, or 
the square which it is to occupy, is attacked by one or more of the opponent's 
pieces, or
if there is any piece between the king and the rook with which castling is to 
be effected.
