Art enthusiasts eager to view Leonardo da Vinci's renowned masterpiece, "The Last Supper," should head to the Convent of Santa Maria delle Grazie. This iconic fresco is displayed in the refectory of the convent and is a UNESCO World Heritage site. Due to its popularity and the need to preserve the delicate artwork, visitor numbers are limited, and advance ticket reservations are required. It's recommended to book your tickets well ahead of your visit, either online or through an authorized ticket agency. While in the area, consider visiting the Church of Santa Maria delle Grazie itself and the nearby Church of San Maurizio al Monastero Maggiore for a more comprehensive art experience.
