Lucca Antiques market takes place over the weekend on the 3rd Sunday of every month & takes place in the middle of the town. It is really good, selling some lovely items from jewellery to furniture. I would recommend a very slow casual walk around (2-3 hours) .
If you aren’t around on the 3rd weekend then it takes place nearby on the other weekends in Tuscany, but Lucca is a great backdrop.
If you don’t have your dog, then bring a child – lots of wonderful gelateria’s nearby for emergencies
Even a bottle of wine for Dad after following Millie around from one jewellery stall to another.
