Later, in 1755, Pope Benedict XIV (whose coat of arms still dominates the main entrance) ordered major restructuring, entrusting the work to Luigi Hostini. In the following years there were installed the court offices and police headquarters. In 1849, Pius IX moved the Ministries of Finances and of the Public Debt here, as well as the Papal Post Offices. After the conquest of Rome by the newly formed Kingdom of Italy, the palace was chosen to become the seat of the "Senato del Regno" (Senate of the Kingdom).
