One of the most interesting things we saw during our trip was a medieval necropolis. It’s not on the usual itinerary — in fact it’s a long way off the beaten path — but I happen to have friends in high places (or in this case, low ones). Nearly every granite outcropping of sufficient size in this field had a grave carved into it. They were remarkably small.
Their age is uncertain, since the original bodies are long gone and there’s nothing to date them. But we do know that they date back to at least the year 1000 AD.
Note of interest: more recent residents of this area used the empty graves for making wine. How very Portuguese.
