Benedetto Innocenzo Alfieri (8 June 1699 - 9 December 1767) was an Italian architect, a representative of the late-Baroque or Rococo style.
[1] In Rome, Benedetto was educated in mathematics and design by the Jesuits; he then moved to Piedmont (living in Turin and Asti) to practice both as a lawyer and as an architect.
[2] He was frequently patronized by Charles Emmanuel III of Sardinia, who commissioned him with the design of the Royal Theater of Turin;[2] the theatre (which was probably his masterwork) burned down in 1936 and reopened in 1973.
He also completed the bell tower of the Church of Santa Anna in Asti; designed the Palazzo Ghilini in Alessandria; helped complete the façade of the Vercelli Cathedral (1757–1763); aided in the decoration of the interior of the Basilica of Corpus Domini in Turin and the decoration of Palazzo Chiablese, adjacent to the Royal Palace in Turin.
He collaborated during his long career with artists such as Luigi Acquisti, Giovanni Battista Borra, and Emilio Usiglio among many.
