Casa Campanini is a highly significant Art Nouveau (Liberty style) building located at 11, Via Bellini in Milan, Italy, designed and built by architect Alfredo Campanini as his own residence between 1903 and 1906. It is considered one of the finest examples of Milanese Art Nouveau, distinguished by its striking decorative features and craftsmanship.
The entrance is famously framed by massive concrete caryatids (statues of female figures) sculpted by Michele Vedani, referencing the earlier Palazzo Castiglioni by Giuseppe Sommaruga. The wrought-iron gate, as well as balcony balustrades and the elevator cage, were designed by Campanini and executed by Alessandro Mazzucotelli, featuring elaborate floral motifs typical of the style.
Campanini was a leading proponent of the Liberty style in Milan and designed other significant works nearby, however, Casa Campanini is seen as his most important legacy.
 
Interesting facts....
The caryatids are sculpted in concrete, which was innovative at the time for such decorative architectural use. Even today it is rare.
