The classic study of patient H.M., who had his hippocampus removed, showed that the hippocampus isn't where memories are stored long-term https://www.ncbi.nlm.nih.gov/pmc/articles/PMC497229/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC497229/ (this was one of the first studies to discover the role of the hippocampus in memory). H.M. was still able to recall memories from before the surgery, and numerous animal and human studies have demonstrated this too. The hippocampus connects to most of the cortex, and there is an entire research area looking into hippocampal replay and how it facilitates consolidation, but there definitely isn't a singular place where memories are stored in the brain long-term.
