Here's a full episode of Time Team as they explore a Bell Beaker settlement in Mallorca, Balearic Islands with William Waldren.
The settlement appears to have had an aqueduct that fed at least two large buildings within a fortress type enclosure. A nearby temple site or complex had an observation post was oriented in the saddle of two mountains, very directly oriented toward Crux, or "The Southern Cross".*
William Waldren basically wrote the history for much of the Balearic Islands [here]
Here's the obituary of William H. Waldren, archaeologist. [here]

* I'll have to do more reading on the various mythologies of the Crux, but in Christian times it was associated with the death of the Sun in the equinox, symbolizing the death of Christ for three days and then his victory over the cross and resurrection. Because Crux disappeared in the Northern latitudes, its myth survived in Greece the longest as the beastial parts of the Centaurus. It nearly completely disappeared from Europe at the very beginning of the Christian era, so it was widely accepted to be a sign. In Greek mythology it is again associated with the sun, but in a less direct way.
As a side, side note...
You'll remember that a number of the funerary Beaker potteries have cross bottoms...
