"The most scary cathedral in the world" - that's what some people call the Cathedral of Otranto. Others call it the "Cathedral of Skulls". We are not visiting churches very often, unless they hide strange stories or unique works of art. The Otrando Cathedral impresses with its amazing mosaic floor and surprises with a dark chapel where walls are crypts filled with HUMAN SCULLS !!! Drastic but when you learn the history of this place and crypts the whole thing makes sense and shows the values ​​guided people of our past. Must See.
