In which country did Leonardo da Vinci spend the last three years of his life?

Leonardo di ser Piero da Vinci more commonly Leonardo da Vinci or simply Leonardo (15 April 1452 – 2 May 1519), was an Italian polymath whose areas of interest included invention, painting, sculpting, architecture, science, music, mathematics, engineering, literature, anatomy, geology, astronomy, botany, writing, history, and cartography.

On 19 December 1515, Leonardo was present at the meeting of Francis I and Pope Leo X, which took place in Bologna. Leonardo was commissioned to make a mechanical lion for Francis I, that could walk forward then open its chest to reveal a cluster of lilies. In 1516, he entered Francis' service, being given the use of the manor house Clos Lucé, now a public museum, near the king's residence at the royal Château d'Amboise in France. He spent the last three years of his life there, accompanied by his friend and apprentice, Count Francesco Melzi.
