The town in the background is called San Gimignano and is a very popular tourist attraction. If you can manage it, go there during the week and not on a weekend. It's very crouded. I think it's one of the most interesting towns I've ever been to, very pleasant to walk throught he small alleys and streets with some very nice shops (and not only touristic shops).
It's got an interesting story to it regarding the towers you can see. The towers used to be the homes of the rich a couple of centuries ago. What normally happened and did in most other villages in the area is when the towns and inhabitants got richer, the towers were demolished and normal houses were built. That's why these towers can only be really seen in San Gimignano. It was too poor at the time to demolish the towers and so they've stayed there until the present day. Now of course, they're a huge touristic attraction and all of the other towns in the area wished they had them too. That's life I suppose.
