By chance, last week I had the opportunity to visit the house Galileo lived in in the last years of his life near Arcetri Observatory in Florence.
I was actually visiting the Observatory where I had been invited to give a seminar.
From the roof of the observatory you can see across the valley to the Villa il Gioiello where Galileo lived from 1631-1642. It's the yellowish building just left of centre.
Here's an 18th century monument to Galileo from when the house was first becoming famous.
