Castling is a special move to protect your king and activate your rook. It's the only time in chess you can move two pieces in one move. The king moves two squares to the right or left and the rook moves directly to the other side of the king. You can only castle if neither the rook or king have moved and there are no pieces in the way. You can also not castle when in check, into check or through check.
