3C324, a giant radiogalaxy at ζ = 1.206 has been suspected by us to be a gravitational lens : in a previous work, we have identified an additional line system at ζ = 0.845 in its spectrum. We present here new observations of 3C324 at CF.H.T. in R broad band imaging and in adequate filters; they strongly suggest that 3C324 is the first example of a multiply imaged radiogalaxy. The 3C324 case is also a fair confirmation that gravitational lensing may well explain the overluminosity of distant
