The Portiflue or Portifluh is approx. 1.2 km southeast of Zullwil.
Here
were found in 1953 prehistoric fragments of pottery. In addition to that were
found pieces of pottery from the 2nd half of the 3rd century AD and a coin of Publius Licinius Egnatius Gallienus (253 - 268
AD).
It is supposed that here was a place of refuge in this unsure roman time.
Since the space is not to large, this place was not used by
much people at the same time
.
Today nothing points out the former use of this place.
