Biblioteca Ambrosiana (Ambrosian Library & Art Gallery), Milan (must see)

In the bustling city of Milan, amidst its grandeur and energy, lies a place of quiet contemplation, the Ambrosiana Library and Art Gallery. Its origins date back to 1603 when local Cardinal Federico Borromeo, who had just returned from Rome's artistic circles, founded this sanctuary of knowledge and beauty. With over 36,000 manuscripts and more than 750,000 prints, the library is a true treasure trove of intellectual inquiry and spiritual reflection. Named after the patron saint of Milan, Ambrose, it is a testament to the intersection of religion, intellectualism, and aesthetics that defined the Renaissance period.

One of the main attractions here is the Codex Atlanticus, a collection of twelve volumes of drawings and manuscripts created by Leonardo da Vinci between 1478 and 1519. Containing the artist's drawings, sketches and fables, it is undoubtedly the largest collection of Leonardo's writings on practically every area of human knowledge: mechanics, mathematics, astronomy, botany, geography, physics, chemistry, architecture and philosophy.

Part of the library is the famous Pinacoteca Ambrosiana, the art gallery, featuring da Vinci's "Portrait of a Musician", Caravaggio's "Basket of Fruit", as well as Raffaello's life-size, pencil and carbon sketch of the "The School of Athens", a full-color final version of which is displayed in the Vatican.

Among other major acquisitions here are Islamic manuscripts, 11th-century diwan of poets and the oldest copy of the 'Kitab Sibawahaihi', plus a complete set of manuscripts from the Benedictine monastery of Bobbio (1606) and those from Vincenzo Pinelli of Padua, comprising more than 800 pieces, including the famous Ilias Picta (Ambrosian Iliad).
