Magical Portugal?

I think I found something exciting.  But I can't be sure -I don't speak Portuguese.  I found a place in Portugal that appears to be loaded with Neolithic monuments and pre-Christian traditions.  In other words, I think I found a sacred landscape comparable to Stonehenge:  the Serre da Estrela National Park in Portugal.

I am interested in pagans, but I am not actually one of them.  For the moment, I'm an unbeliever.  So don't run off shouting about this --I have no proof yet.  Anyway, it's not a discovery if the Portuguese people have always known about it.

I spotted an odd photo on Pinterest.com, a picture of a large brass band making music among giant boulders at Serre da Estrela.  Why would a group named, Philharmonic Band, hike way up into the mountains carrying their tubas and trombones?  Are they following a tradition from the distant past?

Then there were three photos of stones carved to look like human faces.  These could be fake, or just unrelated, but it made me want to see more of this national park.  I read that there are many megaliths near Serre da Estrela (the name translates to Star Mountain.)

The next photo was exciting: dawn at a mountain top lake labeled, Magic Pitcher, in Portuguese.  Has anyone checked the sound quality there?  It looks like the kind of place that would be perfect for a shaman to create echoing sounds.  It has stone cliff walls that hold the lake in a bowl shape.  I had recently heard about research in Norway- they studied the sounds you could make at ancient shrines belonging to the Sami people.  What if Serre da Estrela was a superb place for a shaman from around the year 5000 BCE?

I found cultural links to Celtic traditions all over northern Portugal.  And I don't know if this supports my idea, but I found lots of traces of pre-Christian culture in Portugal.  For example, Portugal has some very strange carnival traditions.  There are masked mummers, something like the Morris Dancers in England.  I would not have noticed any of this without the book, The Dancing Goddesses, by Elizabeth Wayland Barber (pub. by Norton, NY, 2013.)

Then I found a guy who did a PhD on the subject of the megaliths around Serre da Estrela.  He says that all the Neolithic monuments in that area are lined up so that you can watch a bright star named Aldebaran move in relation to Star Mountain.  Seems to me that the shepards of ancient times would have stayed awake nights to keep their animals safe.  The PhD paper explains how to use the bright star as a calendar, so they could tell when it was time to move their animals to the summer pastures up in the mountains.  Only, I can't understand why you'd need a megalithic monument for that?  Couldn't you just wait until the grass turned green, and then take your hundreds of animals up into the hills?

I figure the people of around 5000 BCE would have been rich.  They would have been plump from having unlimited amounts of food.  Maybe their wealth would have looked a lot like that of the Native Americans of Alaska.  They had plenty of extra time for feasting and creating stone monuments.  Anyway, the Riverside Project (a recent research project at Stonehenge) is on my mind.

According to the Riverside Project, the stone houses are for the dead, for your ancestors.  So, could it be that there were wood houses situated near the megaliths in the valley near Serre da Estrella?  And could archaeologists find them?

That's not all- there is an enormous shrine to the Virgin Mary carved into the side of the mountain.  Pinterest has a picture labeled, Our Lady of the Stars.  If that doesn't have a link to ancient pagan beliefs, then I'll eat my hat.  I think it's really interesting to look at the different ways that Christianity absorbed the pre-existing religions.
