The lower part, having also a greater height than the upper part, has ribbing or other vertically oriented interlocking means and the upper part can have the appearance of a natural stone. The shape of either the upper or the lower part may be chosen arbitrarily and independent from each other. The moulding box for the manufacturing or such paving stones is made of two pieces joined together and comprises the corresponding recess. The lower piece comprises an insert for forming interlocking means.
