Minecraft wiki entry for End_City, associated text: End cities usually generate in flat areas, in "midlands" or "highlands" biomes, which are found on larger islands. One may find several cities clustered together, or travel for thousands of blocks before finding one. Unlike other structures, end cities are generated in a noticeable grid. They are only able to be located in chunks numbered 0-8 +- a multiple of 20. For example one possible "cell" for an end city to be generated in is x_chunks=0-8 and z_chunks=80-88 which is equivalent to the coordinates x=0-128 and z=1280-1408. There will never be an end city at for example z=961-1279 or z=1409-1599 because it is outside any "cell".[note 1]
