Final answer:
Da Vinci's Mona Lisa and Annunciation are the paintings stored in the Louvre Museum. The Last Supper, another masterpiece, is located in Milan's Convent of Santa Maria delle Grazie, not the Louvre.
Step-by-step explanation:
Among the paintings by Leonardo da Vinci stored in the Louvre Museum in Paris, the most notable ones are the Mona Lisa and the Annunciation. The Mona Lisa, also known as La Gioconda, is perhaps the most famous painting in the world and is renowned for its enigmatic smile and the subtle use of sfumato technique. On the other hand, the Annunciation depicts the moment the angel Gabriel announces to Mary that she will bear the Son of God, a common theme in Christian art powerfully reinterpreted by da Vinci's skillful hand.
It's important to address that while The Last Supper is one of da Vinci's most celebrated works, it is not housed in the Louvre; instead, it remains in the refectory of the Convent of Santa Maria delle Grazie in Milan. The painting is renowned for its depiction of the reaction of each of the apostles immediately after Jesus announces that one of them will betray him.
