Block, particularly of concrete, for with a number of identical blocks, forming a bond for covering a bank, coast or dike for protection against wave attacks, wherein the block is substantially formed according to a first, preferably regular prism having a first prism perimeter surface and a first prism centre line oriented perpendicular to the prism base, wherein the block comprises a circumferential surface having a circumferential series of side surfaces that in between them define corner areas that extend substantially parallel to the prism centre line, wherein the block in the corner areas forms contact surfaces for abutment against adjacent blocks in the bond, wherein the contact surfaces are situated on the perimeter surface of the prism, wherein at least a few of the corner areas are provided with a recess, which recess extends substantially parallel to the prism centre line from a starting location in the lower half of the block spaced apart from the lower surface to at least near the upper surface preferably up into the upper surface. |
