The invention relates to horizontally and vertically linked paving stones (10). According to the invention, projections (18) and recesses (19) are provided in the area of the bottom part (16) of the paving stones (10) used for a paved surface in order to link said paving stones horizontally and vertically. These projections and recesses engage with each other with a positive fit so as to interlock adjacent stones in a horizontal and vertical direction. The paving stones (10) are characterised in that the width of the joints (32) formed between adjacent paving stones (10) increases in a downward direction so as to form a gap which diverges downwards. This means that the material used for filling the joints can be introduced efficiently and reliably as far as the underside.
