A modular gabion system configured to hold a filler material. The gabion system including multiple framed panels with tab structures positioned and fixed to one side of the multiple framed panels. The tab structures of one panel configured to removably interconnect to another one of the multiple framed panels adjacently positioned thereto to form a gabion structure extending with at least four framed panels. In some embodiments, the multiple framed panels are various sizes to assemble various sized gabion structures. Further, in one embodiment, the assembled gabion structure includes one or more crossmembers to facilitate structural support. In some embodiments, the crossmembers may facilitate coupling gabion structures vertically in a stacked arrangement. In other embodiments, the gabion system facilitates removably interconnecting gabion structures horizontally and/or vertically.
