In southern Spain you can’t dig without hitting some stone age stuff. My town was a known stop for travellers before the Romans took over because of fresh water wells. Eventually a roman road was built about two millenia ago, and still ride on it with my bike for some routes.
No old buildings remain, this was a roadside village and stuff was made cheap and not meant to last, but there is a funeral arrangement from 600 BC that was unearthed and sent to the national museum. More info
In Valheim it was quite real and comfy at the same time. Weird I know.
