Shore erosion control structure has a plurality of block members (3) laid on a beach along a shoreline to form a wall (1) having a plurality of parallel rows and vertical courses. Each of the block members (3) has substantially horizontal, seaward facing openings within which are spaced apart baffles (17). The baffles (17) are removably accommodated in the openings so as to be adjustable and provide tortuous passages through the wall (1) through which water and entrained sand may flow. Water containing entrained sand flowing through the tortuous passages has its energy dissipated so as to enable the entrained sand to be deposited at the landward and seaward sides of the wall (1), as well as in the openings through the block members, thereby preventing the erosion of the beach and, in many cases, enabling restoration of beaches that have been eroded.
