High spatial resolution imaging of 10 3CR galaxies with z = 1 or greater in broad-band filters is reported along with interference filter imaging for three of them. So far, 27 3CR galaxies with z between 1 and 1.84 have been observed with image quality ranging from 0.5 to 1.2 arcsec FWHM. The individual and global properties of these 27 galaxies as seen at the subarcsec level are discussed. A statistical analysis is presented which shows that the z = 1 or greater 3CR galaxies are not distributed at random with respect to the foreground bright galaxies and galaxy clusters. There is as much as nine times more high-z 3CR galaxies around R = 21 or less mag galaxies than would be expected from a random distribution.
