Last year I visited the megalithic sites of Malta (a fun little island!) largely drawn to the Mnajdra Temples which will feature in a forthcoming book. Mnajdra is believed to interact with solar positions as well as helical observations of the Pleiades c. 3000 BCE. A tally system of carved dots found on pillars from its earliest section has been used to support this idea.
The Tal-Qadi Sky Tablet, now in Malta’s Museum of Archaeology, is of related interest. The tablet is named after a now ruinous temple virtually the opposite end of the island to Mnajdra, but its fragmented star configurations are thought to depict the ‘golden gate’ of the ecliptic running between Taurus and the Pleiades. Some believe it was a bit like the Nebra Sky Disk and used to track moon and planets against background constellations c. 4000-3000 BCE. Others think the fragment formed part of a larger zodiac. There’s a good write up about it here: https://en.wikibooks.org/wiki/The_Tal-Qadi_Sky_Tablet
Located more inland and round the corner from Malta’s Hypogeum is the Tarxien Temple with its altars, art and statues.
I Was on my way to Marsaxlokk and chanced upon a lesser-known temple named Borg in-Nadur which, comparatively speaking, remains in a very poor state, but I was surprised to learn it was excavated by Margaret Murray of witch-cult fame.
