"Weird excavations at the construction site of a highway. Symmetrical, look like sculpted out of the ground, 2-4 meters across, up to 1m deep. Only thing that comes to mind are archeological excavations? Or some kind of ground cross section analysis?"
A: "Most definitely archaeological excavations prior to the building of the highway. Most European countries have heritage laws that impose preventive archaeological surveys before major public projects. The shape of the “holes” is the result of a systematic search for archaeological artifacts at different stratigraphic levels."

#32 Many years ago, Black and Decker used to supply one of these (in blue) with their electric lawnmowers and strimmers. This was soon copied by other manufacturers who, obviously, used different colours - usually black. They were later on taken up for other uses, ie: Christmas lights etc.

Didi, my carpenter/architect grandfather had one of these. It killed me to have to leave it behind when we sold the house, but it was HUGE and we couldn't take it with us. :( I hope someone has made better use of it than this.

#28 it's an old heating device for beds.
Pur coals inside and then place under covers.

Derrick, No, those ones don't have holes in the top and are usually flatter. This would make your bed smell like smoke.
