A revetment for an embankment, bank and the like, comprises revetment elements (1) which have parallel bottom (5) and top (4) surfaces and which are arranged according to rows (2, 3) which are positioned next to each other in transverse direction, said rows (2, 3) each extending in longitudinal direction, each revetment (1) element being symmetric with respect to a line of symmetry (9) and asymmetric with respect to a line of asymmetry (10) which is perpendicular with respect to the line of symmetry (9), open spaces (19-21) being enclosed between subsequent revetment elements (1) of a row (2, 3) and between revetment elements (1) of neighbouring rows (2, 3). The lines of symmetry (9) of the revetment elements (1) are oriented in the transverse direction and the revetment elements (1) which are arranged according to a single row (2, 3) have the same orientations with respect to their respective line of asymmetry (10).
