Il Giorno: UNESCO World Heritage bid could disrupt Milan's San Donato plan – the details
The possibility of Chiaravalle becoming a WHS has implications for the construction of a new stadium for AC Milan.
However, I'm not a 100% sure what possible nomination Chiaravalle would be part of. Chiaravalle is not mentioned in Italy's TWHS list. It's major attraction is Chiaravalle Abbey, a Cistercian monastery, but again, I find no TWHS that aims to inscribe Italian Cistercian sites on the WH List.
This comes as a real surprise and it would truly be "the WHS next door" for me, as it is a place close where I lived most of my life and where I went very often. It could be one of those plans "bubbling under" that were discussed on the site some time ago.
So much under, in fact, that I think there is very little concreteness. As Jurre notes, it is not part of anything. It is an important abbey, but I do not really see any potential.
By the way, there is some confusion in these news: Chiaravalle is part of Milan (the big and agricultural zone 5) and
not of San Donato milanese, which is a different
comune (municipality). The project for the new AC Milan stadium falls entirely inside the municipality of San Donato, as this is the whole point of the club: if the city of Milan does not allow (absolutely correctly, in my opinion) to build a new stadium inside its municipality, then they will try to go to a different, but as close as possible, one. Also, the area of the planned stadium and that of Chiaravalle are already separated by a railway and a heck of a big and trafficked
highway (the beginning of A1), so I do not think that Chiaravalle's area can be disrupted more than that. Moreover, any area of interest is to the west of Chiaravalle (parco della Vettabbia / valle dei monaci).
There is a "belt" of hoary Cistercian/Humiliate abbeys around Milan:
Mirasole, Chiaravalle,
Viboldone (a small gem with Giottesque frescoes),
Monluè; further away, one could add
Morimondo. My guess is that a nomination would take them all into account, with Chiaravalle as righteous spearhead. But as much as I love them, I do not see a succesful nomination (but surely do visit them when you are in the area).
Some might sustain this is a political move to block the project for a new stadium in San Donato (but by whom? by those rancorous Milanese not wanting to "lose" a team?). In my opinion a totally useless one, as I described, but I might be underestimating the impact of what comes with a stadium, though nestled between highways. Anyway, more than "bubbling under", it sounds like the slumbering wish of some locals.
But: a very important restoration of the bell tower (the "Ciribiciaccola"), a real Medieval masterwork and landmark,
has been going on for years and is now approaching its end. So maybe...
