BaFe$_2$S$_3$ is a quasi one-dimensional Mott insulator that ordersantiferromagnetically below 117(5)\,K. The application of pressure induces atransition to a metallic state, and superconductivity emerges. The evolution ofthe magnetic behavior on increasing pressure has up to now been either studiedindirectly by means of transport measurements, or by using local magneticprobes only in the low pressure region. Here, we investigate the magneticproperties of BaFe$_2$S$_3$ up to 9.9\,GPa by means of synchrotron $^{57}$FeM\"ossbauer spectroscopy experiments, providing the first local magnetic phasediagram. The magnetic ordering temperature increases up to 185(5) K at7.5\,GPa, and is fully suppressed at 9.9\,GPa. The low-temperature magnetichyperfine field is continuously reduced from 12.9 to 10.3\,T between 1.4 and9.1\,GPa, followed by a sudden drop to zero at 9.9\,GPa indicating afirst-order phase transition. The pressure dependence of the magnetic order inBaFe$_2$S$_3$ can be qualitatively explained by a combination of abandwidth-controlled insulator-metal transition as well as a pressure enhancedexchange interaction between Fe-atoms and Fe 3\textit{d}-S 3\textit{p}hybridization.
