From the comments underneath the video:
“At least three workers were pulled from the rubble, one with a severe head injury. A fourth worker, critically injured, passed away after being rescued 11 hours after the collapse. RIP, Octay Stroici”.
They say Medieval but I wish they’d say what year.
The original structure was built in the 9th c out of a structure built during the Roman Empire. There were other building phases. The first earthquake damage that caused it to be yellow-taped (as it were) was in the 14th c. It was restored a few hundred years later, then damaged and repaired at least once more in the 17th c. I was used quite a bit during the 20th and early 21st century.
