High resolution optical and radio images of the inner regions of NGC 3310 are presented. Subtle but important differences exist in the distributions of the stellar continuum on the one hand and the ionized gas and high energy particles on the other. These data and others suggest that a galaxy-galaxy collision has lead to a major disruption in the inner regions which has not yet fully relaxed even at radii of 0.5-1 kpc where the relaxation time scales are only 10 to the power 7.8 yr. An encounter in which an Irr 1 galaxy is being cannibalized by NGC 3110 provides a scenario for the recent history of the galaxy which is in accord with published observations.
