Galician X-File I: The Tunnel that leads nowhere

The other day we (both administrators of this blog) were having a kilometric long walk when suddenly, from no-where, we reached an open of terrain. That would not be very rare at first because here, in Galicia, the opens of terrain abounds but this one looked a little special ... In it we found a strange, weird and an unusual construction: a tunnel. A tunnel is not rare nowadays, they are used to communicate two distant points that cannot communicate directly because of geographic reasons; an underground passage... but this one did not fulfill any of the conditions.

We surrounded the construction to verify that, in real, it was there; we verified its resistance giving it some blows...

Yes, there it was! It was a tunnel without sense nor utility.
