Ambrosian Library (Accademia Ambrosiana)

First off, it was founded in 1609 by Cardinal Federico Borromeo and named after Saint Ambrose, the patron saint of Milan. The library boasts an impressive collection of over 30,000 manuscripts, including ancient texts, illuminated manuscripts, and codices. Second, the library houses Leonardo da Vinci's original Codex Atlanticus, a compilation of his scientific and artistic sketches. It's a remarkable piece of history, my friends. And here's a fun fact for you: The library's Pinacoteca Ambrosiana also holds a stunning collection of artworks, including Caravaggio's famous painting "Basket of Fruit." It's like stepping into an art gallery within a library. Lastly, a curiosity about the Ambrosian Library is that it features a fascinating exhibit dedicated to the life and works of Leonardo da Vinci, providing visitors with a deeper understanding of his genius and influence.
