Cathedral of Saint John the Baptist

This church was built from 1634 by Guarino Guarini to a complex baroque design, where square basilica plan and Grecian cross segues into circular, octagonal and elliptical forms. This creates a striking light-play, especially in the dome, which Guarini might not be pleased to know is dubbed faccia del diavolo, the face of the devil.

The Palace was built in the 16th century, modernised in the 17th and converted to a museum in 1946. The result is a wacky hybrid of medieval, baroque and bling. You enter via the palace gardens to reach the ticket office. The ticket covers five attractions:
- Galleria Sabauda houses the vast art collection of the rulers of Savoy.
- Chapel of the Shroud is accessed this way, and from a gallery looks into the Cathedral.
- Royal Apartments: gilt, red flock, chandeliers, vast paintings, and everything else to impress.
- Royal Armoury: dating from the 16th century, the 1833 collection of Sardinian king Carlo Alberto.
- Royal Library: this contains some 200,000 print volumes, 4500 manuscripts, 3055 drawings, 187 incunabula predating 1501, 5019 16th-century books, 20,987 pamphlets, 1500 works on parchment, 1112 periodicals, and 400 photo albums, maps, engravings, and prints. It contains several works Leonardo da Vinci's: Codex on the Flight of Birds, his self-portrait, his study for the angel in his Virgin of the Rocks and his study for the angel in Verrocchio's The Baptism of Christ.

This museum houses art from Kandahar, India, Southeast Asia, China and Japan. The third floor shows Buddhist and Tibetan culture. The fourth floor is Islamic and Arabian, mainly bronzes, ceramics and tiles.

The city's oldest and premier theatre, opened in 1753. It was wrecked by fire in 1786 but swiftly rebuilt to the original plan, and from 1936 to 1973 it was the opera house during Teatro Regio's lengthy closure.

A jewel of baroque architecture and sacred art built from 1680 by businessmen anxious to sanctify their dealings - they were, let's stress, "The Pious Congregation of Bankers, Shopkeepers and Merchants of Turin." One theme of the decor is the Magi, bearing the trade valuables without which the Christian church couldn't exist. The chapel was created within Chiesa dei Santi Martiri, a 16th-century Jesuit church. Its best-known artefact is the "calendario perpetuo" made by Giovanni Amedeo Plana in 1831. This predicts lunar phases, tides, days of the week and Christian holy days for 4000 years from Year Zero (1 BC in the Gregorian calendar); thereafter it's askew as it misses an extra leap-day tweak. It ranks among the world's earliest computers, though pipped by Babbage's "difference engine" of 1822.

Fascinating exposition of the tumultuous birth of modern Italy, set in the very building where many events took place: Carlo Alberto and Vittorio Emanuele II were born here, and the first Italian parliament sat here. Garibaldi's campaign was in the context of revolutions and upheavals all over Europe, the greatest of all being the Industrial Revolution. It was a very literary and graphic age, so events are vividly shown in film, photos, political cartoons and other artefacts.
