As you enter the palace, you will notice that it is built in the Baroque style, a form of architecture with loud and elaborate elements designed to astound visitors. Ascend its staircases and visit its ornately decorated royal apartments and halls. The 19th-century Ballroom, the Throne Room, and the Sala del Caffe, or the coffee room are some must-see spots in the royal palace. Most rooms contain valuable paintings, dazzling low-hanging chandeliers, frescoes, and intricate gold gilded moldings on the ceilings. Rooms are filled with plush furniture and valuable artifacts such as porcelains, crystals, and timepieces scattered across the room.

Near the entrance to the palace is the Chapel of the Holy Shroud, an adjoining building that holds the Shroud of Turin, a sacred relic believed to be the veil with which Jesus Christ was buried. The chapel is a circular enclosure capped with a towering dome. The chapel features large lunettes or semi-circles at the base of the dome with oculus-like windows in the middle of each. The upper dome consists of six levels of crisis crossing arches that lead to the glowing lantern at the very top. In the center of the chapel is a beautiful altar made of black marble. Positioned in the center of the altar is the Shroud of Turin encased in a glass container with a golden grate.

At the end of the right wing of the palace is a long narrow hall filled with armored cavalrymen and an arsenal of melee weapons. Welcome to the Royal Armory. It was founded by King Charles Albert with the object of displaying the rich martial history of the region and surrounding areas over millennia. He initially vested his own collection of weaponry from Turin and Genoa's arsenal in the armory. It later came to include prehistoric and medieval objects, as well as armaments used by the Dukes of Savoy and the various sections of their army. It also contains rare weapons that were transferred as diplomatic gifts. The sword of San Maurizio, a 16th-century pistol of the emperor Charles V and Girolamo Martinengo's breastplate dating from 1540 are a few of the armory's most treasured possessions.

The collection of archaeological artifacts began with deliberate campaigns by Emanuele Filiberto and his son Carlo Emanuele I between the 16th and 17th centuries to create a central location of ancient artifacts of Turin and historically significant regions. The museum is divided into three sections - the Archaeological Gallery, the Archeology section, and the Pavilion of the Piedmontese. The gallery will lead you down a hallway full of statues, busts, and remnants of ancient structures from the Piedmont area, Turin, the Mediterranean, and the Near East. As part of the museum, you will also find a large study hall dedicated to research and documentation with a restoration laboratory and a photographic cabinet.

The Royal Library is next up. It is a quaint-looking hall that was established in 1842 by Charles Albert of the House of Savoy. Lining the walls are segmented wooden shelves enclosed with glass. Behind them lie a collection of 200,000 volumes of books, documents, periodicals, pamphlets, architectural drawings, and illuminated manuscripts belonging to the House of Savoy. The library was built in order to boost the cultural standing of the nation, as a part of a number of reforms and the creation of institutions. The self-portrait of Leonardo da Vinci and his Codex of the Flight of Birds are some of the most esteemed documents in its archive.

The Sabauda Art Gallery, initially called the Regia Pinacoteca, was also founded by Charles Albert in 1832. Its repository of works began to grow through acquisitions of art collections from various well-to-do people and industrialists. The gallery holds over 500 artworks by Italian and European artists and follows a chronological order, displaying work from the 14th century onwards up to the 20th century. It features famous paintings from artists such as Beato Angelico, Filippino Lippi, Paolo Veronese, and Sandro Botticelli. The collection's most notable work is perhaps the portrait of Venus by Botticelli.

End your tour by visiting the expansive gardens surrounding the Royal Palace. With abundant space, sprawling nature, and aesthetic fountains and statues, the Royal Gardens is the best place at the Musei Reali for much-needed rest and relaxation. The Royal Garden consists of the Ducal Garden in the north, the Eastern Garden and the Cavallerizza Garden to the east, and the Boschetto with the Low Gardens in the northeastern part of the area. One can find a number of native and exotic tree and plant species here that add to the lush greeny of this public space. Make sure to see the 18th-century fountain established by Simone Martinez and a contemporary art installation by Giulio Paolini while you're there.
