It was commissioned by lawyer Cataldo Baglio, a member of one of the most prominent families of the local elite, in the second half of the 19th century—specifically between 1887 and 1888—and was named after his daughter, Isabella. The building stands on a rocky rise in an area inhabited since the Bronze Age. Built on two levels, its façade, made of calcarenite, features pilasters and cornices in Liberty style and floral decorations carved in tuff, while the interior was completely remodeled during the 1980s.
