A block for constructing a retaining wall comprises a front wall and a counterfort protruded from a back side of the front wall, wherein the counterfort is provided with a plurality of reinforcing steel bar insertion holes each of which has upper and lower ends thereof open-ended. Each reinforcing steel bar insertion hole disposed in a front wall side away from a neutral force plane is either a tapered hole increasing in diameter thereof from the upper opening to the lower opening thereof. Each reinforcing steel bar insertion hole disposed in a rear end side away from the neutral force plane is an inverse-tapered hole having a diameter increasing from the lower opening to the upper opening. The above-mentioned blocks for constructing the retaining wall are stacked on an upper surface of a footing foundation made of steel bar reinforced concrete, a plurality of anchoring steel bars protrudes from the footing foundation and a plurality of connecting steel bars is inserted into the steel bar insertion holes which are vertically aligned with each other and a filler is filled in the steel bar insertion holes to construct the retaining wall. Due to such a construction, the hardened filler is prevented from sliding relative to the steel bar insertion hole and the rigidity of the junctions where the abutting surfaces of the blocks for constructing retaining wall merge is increased to provide a rigid body integrally formed with the footing foundation.
