Francesco Borromini was featured on the 6th series 100 Swiss Franc banknote, which was in circulation from 1976 until 2000.
This decision at that time caused polemics in Switzerland, started by the Swiss Italian art historian Piero Bianconi.
According to him, since in 17th century the territories which in 1803 became the Canton Ticino were Italian possessions of some Swiss cantons (Condominiums of the Twelve Cantons), Borromini could neither be defined Ticinese nor Swiss.

He is the subject of the movie La Sapienza by Eugène Green released in 2015.
