A crux immissa or Latin cross
A Latin cross or crux immissa is a type of Christian cross in which the vertical beam sticks above the crossbeam, giving the cross four arms. Typically, the two horizontal and upper vertical arm are the same length, although sometimes the vertical is shorter; however, the lower vertical arm is always much longer than any other arm.
