A gravity-type quay wall comprising a rubble base stage (3) extending from the sea bottom. A lower part (1a) is constructed on the rubble base stage (3) by stacking cell block units (4) wherein each of the cell block units (4) have four walls defining a vacant space therein for filling with rubble (5). Two of the walls of the cell block units (4) are side walls (6,6a), each having one of a female key (13) or a male key (14) for mating with adjacent cell block units (4). In an upper part of a top staged cell block unit (4a) is a depressed portion (7). An L-shaped shelf-style middle part (1b) is settled on a top surface of the rubble (5) of the lower part (1a) wherein the rubble (5) is filled halfway in the depressed portion (7). An upper part (1c) is settled on the middle part (1b) with the same length and width thereof.
