On the occasion of the 110th anniversary of his passing, in the column From the Register to History, we published the death certificate of Guglielmo Calderini (1837-1916), a Perugian architect and spokesman for post-Unitarian eclecticism, who linked his name to some of Italy’s most ambitious public architecture, including the Palace of Justice and the external quadriporticus of the Basilica of St. Paul Outside the Walls in Rome.
