A protective wall assembly (8) for protecting an embankment (6) to prevent scouring of the embankment (6) during high water flows such as experienced in floods or tidal waves. The protective wall assembly (8) comprises a plurality of block assemblies (10) each having a body (11), a top surface (30), and a bottom surface (32). Each block assembly (10) further includes four side faces (34,34a,34b,34c) interconnected by four intermediate faces (13,13a,13b,13c) to define an eight-sided body. Each intermediate face (13,13a,13b,13c) has a bore (21,22) extending perpendicularly thereinto. A first connecting device (42) engages the bores (21,22) in a first pair of intermediate faces (13,13b) of a first pair of block assemblies (10A,10C). The length of one (21) of the bores (21,22) is different than a length of the other of the bores (21,22). The protective wall assembly (8) provides an environmentally friendly structure harmonized with the surrounding scenery.
