My comment few days ago [1] now look strangely prophetic. We only need to find 3 more Stonehenges. [1] https://news.ycombinator.com/item?id=49507810#49510204 https://news.ycombinator.com/item?id=49507810#49510204

Stonehenge is always mentioned as reference but you have much much older ones: Göbekli Tepe (Turkey) ~9600 BCE Almendres Cromlech (Portugal) ~5900 BCE

    This reminded me of when the governor of Amazonas told the press that Amazon should pay them royalties for using the state’s name https://youtube.com/shorts/fQXcpdtCcTs https://youtube.com/shorts/fQXcpdtCcTs

  I found it to be very fascinating how names like Amazon, Alibaba, Tesla, Titanic, Mustang et al had almost crushed the original meaning that, once encountered, you instantly recognized it as a brand/product unless clear context is provided.

I love these random appearances of Wikipedia pages on the HN front page. I'm Brazilian, and this is the first time I've heard of this park.

  Same! Somehow I had never heard of this. Will have to try and visit someday! Also, lol @ the name of the river near that site. (For the gringos: "Rego Grande", "rego" officially means ditch/trench, but nowadays it's much more commonly used as slang for butt crack. So, it's the Large Butt Crack river. Which I guess tracks for Brazil :P)

>>On the winter solstice of December 21, the shortest day of the year in the northern hemisphere,[clarification needed] the shadow of one of the blocks disappears when the sun is directly above it. This is not quite right. On that day the Sun is directly above São Paulo. At the archaeological site: Latitude = +2.62°, Solar declination ≈ −23.44°, Difference = about 26.06°. Therefore, at solar noon: Sun altitude ≈ 90° − 26.06° = 63.94°. Consequently, at that particular latitude, a normal vertical stone cannot have its shadow disappear because the Sun is directly overhead on December 21.

  That assumes a perfectly vertical stone, which is not really indicated by the article's description of the stone placements.
