Galaxy mergers are often considered in the literature as ideal places to study diverse starburststriggered during the merger events. In that sense, the intermediate-age merger remnant NGC 1316 constitutesa perfect case to study complex large-scale star formation events in the Local Universe. In a series of previousworks we confirmed the existence of a complex globular cluster (GC) system associated with NGC 1316, whichis dominated by the presence of an unusual young (≈ 2.1 Gyr) and metal-rich subpopulation (−0.5 < [Z/H]
