It may have taken the Romans 400 years to build the Capitoline Museums, after they were designed in 1536 by Michelangelo, but the wait was worth it.

 This outstanding collection of art and archeological museums, which started with a papal donation in the 15th century, can be found at Piazza del Campidoglio atop Capitoline Hill. 

The collections include medieval and Renaissance art, old Roman statues and jewels.
