The Mausoleum of Bela Rosin is a neoclassical building from the year 1888. It is an exact copy of the Pantheon in Rome, and was designed by the children of Rosa Vercellana (wife of the king of Italy Vittorio Emanuele II), known as, in Piedmontese dialect, “Bela Rosin”. The mausoleum has a diameter and height of approximately sixteen metres; the design of the structural recovery intervention was entrusted to Prof. Eng. Francesco Ossola, who followed the original project. Today the Bela Rosin Mausoleum, under the Superintendence for Artistic and Architectural Heritage of Piedmont, is managed by the public libraries of Turin, which organize events, conferences, exhibitions, readings, concerts.
