Relazione dell'Ufficio Regionale per la Conservazione dei monumenti delle Marche e dell'Umbria (1891-92,1900-901)
A government report from 1903 published in Perugia by the Regional Office for the Conservation of Monuments of the Marche and Umbria, compiled under architect Giuseppe Sacconi and aimed at heritage officials and specialists. Its pictures are pen-and-ink architectural drawings and a few photographs of medieval castles, churches, and tower houses, with plans, elevations, and carved details that a designer could study for stone massing, arched openings, and decorative masonry patterns.
