Palazzo Castellesi

Palazzo Torlonia (also known as the Palazzo Giraud, Giraud-Torlonia or Castellesi) is a 16th-century Renaissance town house in Via della Conciliazione, Rome, Italy. Built for Cardinal Adriano Castellesi da Corneto from 1496, the architect was Andrea Bregno, although others have attributed the design to Bramante.

The style of architecture was influenced by that of the papal chancery, the Palazzo della Cancelleria, one of Rome's first Renaissance palaces, which had been completed a few years earlier. The palazzo's arcaded inner courtyard has been attributed to Raphael.

In 1504, before its completion, the Cardinal (who had fallen from papal favor) presented the palazzo to King Henry VII of England. The English king Henry VIII later handed it to Lorenzo Campeggio, England's last Cardinal Protector. He lived in the unfinished palazzo from 1519 to 1524. Following England's split from the Church of Rome, it remained in possession of the Campeggio family until 1609.

From 1609 until 1635, it was owned by the Borghese family. In 1760, it was purchased by the French Giraud banking family.
