Franciscan Church
Gothic church of Holy Trinity, by the locals simply called the Franciscan church, was built in the fourteenth century. It is one of the most valuable monuments in the city. First of all, because it contains the remains of the Opole Piasts. There are the tombs of the founders of the Franciscan church and monastery in Opole - Bolesław I, Bolesław II and Bolesław III, and of Princess Anna Oświęcimska. Under the church presbytery, other Opole princes were buried including Władysław II Opolczyk, the founder of the Jasna Góra sanctuary, and Princess Elżbieta, granddaughter of King Władysław Łokietek. There is also the oldest surviving early Gothic fresco from 1320 in Silesia. It depicts the Passion of Jesus, next to which stand his Mother and St. Jan. In the Franciscan church, it is worth visiting the chapels of Our Lady of Częstochowa, the chapel of St. Jadwiga and the chapel of St. Anna called Piastowska. It is also worth knowing that during the Swedish Deluge, the chancellery of King Jan Kazimierz was located in the Opole monastery. It was here, in the monastery refectory in 1655, that the so-called royal universal calling the Polish nation to rise against the Swedes.
