One of the artistic treasures of the city of Florence, the "Gates of Paradise", has been restored after being lost to the public for nearly three decades.
The magnificent set of doors, weighing 9 tonnes, are cast in bronze and coated in gold. They have been described as one of the defining works of the Italian Renaissance.
The BBC's Alan Johnston has been given an exclusive look at the newly renovated masterpiece.
