Abstract: A plurality of pavings stones are organized in an array to form a walkway having the appearance of cobblestones. Each of the prime elements of the walkway includes an elongated stone having the general appearance of three hexagonal stones joined together. The sides allow the stones to be interfitted to with adjacent stones being offset one-half a hexagon or more. The top surface of the stones includes three rounded projections above the planar sidewalls so that earth, sand and the like which falls into the cracks between the projections will give the walkway the appearance of cobblestones.
