Facing Noto's celebrated cathedral is Palazzo Ducezio, designed in the mid-18th-century by Vincenzo Sinatra and inspired by French palace architecture of the 17th century. The lower-level building was only completed in 1830, while the top floor was built in the first half of the 20th century. The palace features a partly convex facade, its graceful arches supported by Ionic-capital columns. It now houses Noto's town hall.
