Palazzo Modello is a historic building located on Piazza Unità d'Italia in Trieste, Italy.

The building was erected between 1871 and 1872 during urban redevelopment works affecting the square.

The building stands on a site once occupied by a late medieval chapel dedicated to Saint Peter, itself the ancient namesake for the square, and a seventeenth-century church dedicated to Saint Roch.

[1][2][3] Following the demolition of the two religious buildings in 1870, the Municipality of Trieste, which owned the area, commissioned architect Giuseppe Bruni to design a building that would serve as a model for the others to be constructed around the square in the following years.
