The aim of the article is to verify the existing thesis about round traces around ghotic church portals. The author has catalogued over 160 religious buildings from northern Poland and tabulated the gathered data. He has also made an attempt to explain the reasons for which a portal was an especially appropriate place for making pit traces. The interpretation has been based mainly on Biblical texts, which repeatedly emphasise the significance of the place leading from the profane to the sacred world. The speculations have been complemented with a detailed list of locations visited by the author and the tables specify the exact number of traces on the church walls with consideration of their geographical orientation.
