We had the privilege to visit the Biblioteca Briganti, part of the museum complex of Santa Maria della Scala. It’s a treasure trove of resources, including the amazing volumes of Piranesi’s views of Rome, and many books related to Siena’s history, artists, and craftspeople. It also houses the “Librartis” collection of contemporary artists’ books. For more info on the library: https://www.santamariadellascala.com/en/services/#fototeca
