As impressive an example of Renaissance architecture as you’ll find in Rome, this huge palazzo was built for Cardinal Raffaele Riario between 1483 and 1513. It was later acquired by the Vatican and became the seat of the Papal Chancellory. It is still Vatican property and nowadays houses the Tribunal of the Roman Rota, the Holy See’s highest ecclesiastical court.
Until April 2016, the palazzo is hosting an exhibition dedicated to machines designed by Leonardo da Vinci. But if that doesn't appeal, it's worth nipping through to the courtyard to take a peek at Bramante’s glorious double loggia.
Incorporated into the palazzo, the 4th-century Basilica di San Lorenzo in Damaso is one of Rome’s oldest churches.
