GPR survey inside Frombork Cathedral in 2013


    In 2013, a non-destructive GPR investigation was carried out over the floors inside the Cathedral in Frombork. The investigation was performed to a depth of 3 m using an 800 MHz antenna. During the studies, the main focus was to find the place conventionally known as the lectorium (reading room). The investigation has confirmed the location of the strong anomalies that were identified during the first GPR study using the 250 MHz antenna in 2005. The paper discusses the methods and stages of the research. Three selected GPR cross-sections are shown as examples together with the map of anomalies in the area called the lectorium.
