3C324, a giant radiogalaxy at z = 1.206 has been suspected by us to be a gravitational lens: in a previous work, we have identified an additional line system at z = 0.845 in its spectrum. We present here new observations of 3C324 at C.F.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 radiogalaxies.
