We have taken deep R-band images of fields around five radiogalaxies: 0956+47, 1217+36, 3C256, 3C324 and 3C294 with 1 < z < 2. We found a statistically significant excess of bright (19.5 < R < 22) galaxies on scales of 2 arcmin around the radiogalaxies. The excess has been determined empirically to be at ≳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.
