This knowledge graph contains data about Italian bells and bell towers. Data about bells refer to both measurable, intrinsic aspects such as weight, materials, conservation status, as well as properties deriving from interpretation situations, such as authorship attribution, dating, execution techniques, and their related objects (e.g. bibliography). The Bells knowledge graph is integrated in the ArCo knowledge graph.
