This is a Chess 960 position. Click your king to see which rooks can castle. Drop the king on the rook to castle.
In opera mate, a rook checkmates the king. The rook is next to the king, but can't be captured, because it is protected by a bishop (or a queen on the diagonal), which also prevents the escape.
