It was the dream of the late artist couple, Bulgarian-born Christo and his French wife Jeanne-Claude. As they gazed out of their window in the early 1960s, they imagined wrapping Paris's Arc de Triomphe monument in fabric. They laid out detailed drawings and instructions on how to transform the landmark structure and today, their vision has been posthumously realised. We take a closer look.
Also on the programme, it's that time of year in France where for two days thousands of historic monuments across the country – including gardens, museums, theatres and even the Paris sewers – hold free open days for the public. Our reporters take us behind the scenes at Paris's iconic Châtelet Theatre.
