Megaliths
Huge rough stones set upright, in circles or as houses for the dead

How to recognise it
- Standing menhirs in rows or circles
- Dolmen: slab walls under a capstone
- Earth mound over a stone passage
- Aligned to solstice sunrise or sunset
- Spirals and lozenges pecked into stone
Why it emerged
Atlantic Europe's first farmers settled down and raised lasting monuments to ancestors and the solar calendar. Moving stones without metal or wheels took hundreds of people, which meant chiefs and communal feasts.
