Low resolution (171 A/mm) IDS spectrograms, medium resolution (56 A/mm and 28 A/mm) long slit image tube spectrograms, and electronographic direct images in the visual and blue spectral range have been obtained of the radio galaxy IC 5063. According to the results of these observations the main body of IC 5063 is a slowly rotating giant elliptical or S0 galaxy. At its center is an active nucleus which is surrounded by a rapidly rotating disk of gas and dust filaments. This system shows many similarities with NGC 5128 (Cen A). From the observations, it is concluded that the present structure of IC 5063 is most likely the result of the capture of a gas rich system by an oblate giant elliptical or S0 galaxy.
