History

 * 1075: Established as Diocese of Płock
 * During the German occupation of Poland (World War II), the Archbishop of Płock Antoni Julian Nowowiejski and the auxiliary Bishop were imprisoned in the village of Słupno, and then in 1941 murdered in the Soldau concentration camp, where also many other priests from Płock were killed. Nowowiejski and Wetmański are now considered two of the 108 Blessed Polish Martyrs of World War II by the Catholic Church. The Cathedral's ancient treasury, church archives and the diocesan library in Płock were robbed by the Germans, and taken to museums in Königsberg, Wrocław and Berlin.
 * 2018: Płock Cathedral along with the entire Wzgórze Tumskie ("Tumskie Hill") listed by the President of Poland as a Historic Monument of Poland.
