A wave-motion reducing structure comprises wave-motion reducing means (30 ) suitable for being laid on a coastal bed and restraining means (20, 22) su itable for restraining the wave-motion reducing means on the coastal bed. Th e wave-motion reducing means (30) are arranged so as to be inclined, in use, against the direction of the sea current which strikes them. A wave-motion reducing system comprises a plurality of wave-motion reducing structures arr anged in a row lengthwise and in a manner such that the wave-motion reducing means (30) adopt a substantially parallel configuration and oppose the moti on of the current.
