An Umbrian pal of ours has provided her update about the current state of poor, quake-stricken Castelluccio. We'd assisted her daughter's thesis by giving a requested written testimonial about our time there, one which was part of a package sent to the government in hopes of their commencing onsite restorations. Hopefully, those who may be Umbria-bound may benefit from the below info.
I am done. The end.

'Castelluccio di Norcia-- I often go there as a base to explore the surrounding mountains (Monti Sibillini), which I do love (I practice alpinism, climbing, hiking). The ancient stone houses of the village have been almost totally ruined by the earthquake of 2016, the ruins have been partially removed and the shops/restaurants have been moved to temporary structures (which are very solid and nice to see) in the main square of Castelluccio and in a nearby modern structure, newly built, called "deltaplano" who is walking distance to the village. There are some restaurants offering excellent local food (Norcia delicatessen, the renowned lentil of Castelluccio, cereals, cured meats, honey and others, coming form the mountain territory), with an amazing view of the mountains - Monte Vettore is the highest one - and the famous Pian Grande di Castelluccio, with the stunning wild flowering in late June, early July, which attracts many visitors.
There is a project to rebuild the entire village with strict rules to prevent earthquake damages, it has been discussed in detail and I hope in a few years, the village will be gradually and totally rebuilt.
Despite the fact of being ruined, Castelluccio di Norcia still attracts many visitors every year.'
