Francesco La Grassa

Francesco La Grassa (1876–1952) was an Italian engineer and architect active between the late 19th and mid-20th century, known especially for his contribution to the development of Liberty style and early modern architecture in Sicily.

Working primarily in Trapani and later in Rome, he combined Liberty decorative motifs with early reinforced-concrete construction, particularly in staircase design. His work forms part of the broader architectural renewal of western Sicily in the early 1900s.

Notable works in Trapani include the Palazzo delle Poste, the Casina delle Palme (also known as Chalet Fiorino), and the Palazzo Montalto, as well as the reinforced-concrete helical staircase he designed in the Villino Nasi. He also intervened on the historic Palazzo Ducezio in Noto, adding a second floor to the original 18th-century construction by Vincenzo Sinatra between 1949 and 1951.
