@stux Huh! and they probably had to bring those stones from very far away! I have seen similar structures in west Iberia. Here they are not so common (if any).
But I used to go to swim here:
Those pools were built by the romans to keep the fish alive!

@stux They could be just pre-industrial, medieval, muslim or even roman
@stux I find old bricks at the ravine, brought by the occasional flash floods which still have finger marks on them, because they were hand made.
@stux I found records of the manor (for lack of a better word) next to where I live, from the 13th century. And that is normal.
