An essentially quadrate paving stone having a corresponding base block (21) is provided on all four side surfaces (25, 26) with flange-like, upright spacers (22) which are spaced apart from each other at intervals corresponding approximately to the width of the spacers, making it possible for them to make an interlocking connection with adjacent shaped paving stones of the same type. Furthermore, the bottom side (24) of the paving stone features a number of transverse, gutter-like depressions resulting in the formation of ribs between these depressions. This creates an additional dentification, or anchoring, in the bed surface of the installed paving stones.
