Our existing WFPC2 F814W data provides compelling evidence that the luminous IRAS source FSC 10214+4724 at a redshift of z=2.3 is a gravitationally lensed quasar. Because of the high magnification of this source and its strong rest frame optical --UV emission features, further HST observations provide the opportunity to study the continuum and ionized gas structures in this source on physical size scales previously reserved only for the nearest AGN. We propose to use the NICMOS 1 & 2 cameras and the F113N, F164N, F110M, F145M, and F204M filters to image FSC 10214+4724 in the light of redshifted NeV 0.3426Mum, OIII 0.5007Mum and the nearby continuum. Coupled with the planned GTO HAlpha+NII observations in the F215N NICMOS filter, these data will enable us to construct a picture of the Narrow Line Region over a wide range of excitation and density and map out the morphology of the line and continuum emitting zones on scales as small as 50--100pc at z=2.3 -- an order of magnitude finer scale than would be possible without the intervening gravitational lens.
