Palazzo Castiglioni in Milan is a celebrated Art Nouveau (Liberty style) palace designed by Giuseppe Sommaruga between 1901 and 1903 for entrepreneur Ermenegildo Castiglioni. The two figures above were located above the entrance representing “Peace” and “Industry,” earning the nickname “Cà di ciapp” (“house of buttocks”) from locals. Public outrage forced their removal and replacement by floral motifs; the figures now reside at Villa Romeo Faccanoni.
Really interesting as they serve no practical function such as supporting a balcony as is more typical. They also have such natural poses.
 
Interesting fact....
Perhaps watershed moment between the traditional and modern at a time of changing social values. Now cherished as an iconic part of Art Nouveau history
