Sundays in Tuscany

Define places. Brand stores in cities and middle-size touristic towns (think at Siena as an example) will be open; small shops catering only to locals will be closed almost everywhere.

I mean that the village hardware store will be closed, but the shop selling the local specialties will be open.

Obviously museums, restaurants and most bars are open on Sundays. Otherwise they'd loose money.

Pienza montalcino San Querico monticchielo.
Im thinking montepulciano is big enough to be open

Those villages live on tourism and all places catering to tourists will be open.

Thanks for your help! Much appreciated!
