Sistine Chapel: Cleaning the frescos after closing time

More than six million people visit the Sistine Chapel each year - making it the third most-visited museum in the world.

This puts a strain on the health of the famous frescos.

So the Vatican Museums rely on modern technology and a small team of experts to monitor the world-renowned frescos.

The BBC's Sara Monetta got exclusive access to witness how Michelangelo’s work is being looked after.
