There are many places in Portugal which
are interesting seen from a geographical point of view.
– Olivença/Olivenza region, where Portugal and Spain never agreed
on the border.
– Rio de Onor/Rihonor de Castilla,
which form practically the same village divided by the border and
inhabitants own fields on the opposite side of the border.

– Barrancos, a big
'finger' into Spanish territory with a peculiar dialect
