I would say that it is not Barceloan city, it is already outside.. probably Bellvitge... though a full AVE can not take that far...maybe it is an S!"0 for Altaria travels, it can certainly be El Prat del Llobregat getting close to Bellvitge.
That would be my bet :)
A pleasure I therefore claim to show, not how men think in myths, but how myths operate in men's minds without their being aware of the fact. Levi-Strauss, Claude
Well.. I just got the point exactly...it was this or either a little to the south when it is clsoer to El Parat del Llobreagat.. it little bit to the south in your map.
