  We have taken deep $R$-band images of fields around five radiogalaxies:
0956+47, 1217+36, 3C256, 3C324 and 3C294 with $1<z<2$ . 0956+47 is found to
show a double nucleus. Our data on 1217+36 suggest the revision of its
classification as a radiogalaxy. We found a statistically significant excess of
bright ($19.5<R<22$) galaxies on scales of 2 arcmin around the radiogalaxies
(which have $R \approx 21.4$) in our sample. The excess has been determined
empirically to be at $\gtrsim 99.5\%$ level. It is remarkable that this excess
is not present for $22<R<23.75$ galaxies within the same area, suggesting that
the excess is not physically associated to the galaxies but due to intervening
groups and then related to gravitational lensing.
