The author presents a compact, archival-based study of a castle, its architecture, and its art collections. Beginning with early origins and ownership changes, the narrative reconstructs structural developments and renovations, describes architectural and sculptural features, and catalogs paintings, decorative arts, and museum holdings assembled there. Research in state archives and cross-references with other repositories support attributions and provenance, while short topical chapters and selected highlights offer readers an accessible account of the site’s material culture and administrative history.
