Da Vinci's 'Last Supper' painted in late 1400s is viewed by 460,000 visitors each year

Located in the former Dominican convent of Santa Maria delle Grazie in Milan, Italy, the painting is 15 feet high. It stretches roughly 29 feet wide.

Da Vinci painted the fresco between 1496 and 1498 to represent the last dinner between Jesus and His disciples.

To keep the painting maintained at the right temperature, only groups of 25 visitors may view the masterpiece every 15 minutes, according to Milan-Museum. 

"The 'Last Supper' and the Pinacoteca di Brera receive 1 million visitors a year, and take in more than 10 million euros ($10.5 million) in revenue," said Crespi.
