Reliquary of St. Sigismund: treasure of Płock and medieval crown mystery

The reliquary of St. Sigismund ranks among Masovia's most valuable monuments and was one of the pillars of medieval Płock's religious identity. Rev. Canon Stefan Cegłowski, dean of Płock cathedral and art history lecturer, discusses the remarkable history of the reliquary and the mystery of a crown far older than it, which may be connected to the legend of King Arthur.
