We present new HST STIS/MAMA near-UV images and archival WFPC2 V and R bandimages which reveal the presence of four star forming regions in an arc alongthe edge of the dust lane in the giant (4 Mpc) radio galaxy 3C236. Two of thestar forming regions are relatively young with ages of order 1E7 yr, while theother two are older with ages of order 1E8 - 1E9 yr which is comparable to theestimated age of the giant radio source. Based on dynamical and spectral agingarguments, we suggest that the fuel supply to the AGN was interrupted for 1E7yr and has now been restored, resulting in the formation of the inner 2 kpcscale radio source. This time scale is similar to that of the age of theyoungest of the star forming regions. We suggest that the transport of gas inthe disk is non-steady and that this produces both the multiple episodes ofstar formation in the disk as well as the multiple epochs of radio sourceactivity. If the inner radio source and the youngest star forming region arerelated by the same event of gas transport, the gas must be transported fromthe hundreds of pc scale to the sub-parsec scale on a time scale of 1E7 yr,which is similar to the dynamical time scale of the gas on the hundreds of pcscales
