A method of making a concrete block having a three-dimensional patterned face; the method comprising steps of: (a) providing a mold having a plurality of solid aperture-free side walls defining a mold cavity; the mold including: an open mold bottom closed by a pallet; and, a mold surface having a three-dimensional pattern thereon with: a mirror image of the three-dimensional patterned face; and, a maximum relief, in the three-dimensional pattern, of at least about 0.5 inch; (b) introducing dry cast concrete into the mold cavity; (c) compacting the dry cast concrete in the mold cavity to form a pre-cured concrete block with the mold surface having the mirror image of the desired block face forming the desired three-dimensional patterned face on the pre-cured block; (d) discharging the pre-cured block from the mold cavity onto the pallet; and, (e) curing the pre-cured concrete block.
