It is impossible to summarize the relevance of his figure in a few words: suffice it to say that any latitude in the world one spoke of Architectural Conservation, his name was unfailingly mentioned.
Graduated in architecture at the University of Rome La Sapienza in 1967, he has been full professor of Monuments Restoration since 1980, training an entire generation of students, not only Italian.
He has directed or acted as consultant for important architectural restoration sites in Italy and abroad.
He has written hundreds of scientific essays, many of them fundamental, with a marked aptitude for systematizing stories and theories of this discipline. Prominent among all of them is the monumental Trattato di restauro architettonico, that he directed for UTET starting in 1996 and which, with appendices and updates, reached 12 volumes in 2011.
His deep culture, wisdom, and balance, combined with a subtle and bright irony, will be painfully missed by all those who care as much as us about built heritage.
