There is who climbs and who goes downhill. But it's a paradox when you climbed and went downhill at the same time. It's like an Escher draw, there is a downhill street near Paternò (Catania) which actually would be climbed. We explain it better. When you arrived in a certain part of this street, if you switched off your car and left it in neutral, instead of sliding down, you mysteriously would go up again.
Behind an enigma there is always a story. People of that zone tell
The Paternò street is not the only "climb and downhill street". Other cases are signalled in Santa Maria di Licodia, near Schettino, again in the Province of Catania, in Villafranca Tirrena, near Messina, in the street in front of the cemetery of Serro and in Francofonte, near Siracusa. There would be around 20 places in all Italy where someone registered this strange phenomenons.
But also this time science can explain. It would actually be an optical illusion, in which seems that gravity attraction seems to be inverted. What appears as a climb, would actually be a slight downhill. The illusion could be caused by a particular conformity of the landscape or other geographically variables. It's also true that traditional measurement instruments behave like the autos, so we should verify with other expansive and long studies about gravity, to verify the presumed abnormality of this phenomenons. So, the case is already open.
