In 1983 French president Francois Mitterand commissioned a major renovation of Paris' most famous art museum, the Louvre. But the resulting great glass pyramid, designed by American architect IM Pei, caused a storm of controversy, dividing Parisian public opinion as the Eiffel Tower had done a century earlier. Louise Hidalgo talks to IM Pei's colleague and friend, Yann Weymouth, who worked with him on what is now recognised as one of the great landmarks of the city.

On 7 December 1990 the dissident Cuban novelist and poet Reinaldo Arenas killed himself in New York after years of suffering from AIDS. Before fleeing Cuba, Arenas had been jailed for his homosexuality, sent to re-education camps and prevented from writing. He left behind his autobiography - Before Night Falls - a powerful denunciation of Fidel Castro’s regime which later became a successful film. Simon Watts talks to Arenas’ friend and fellow writer, Jaime Manrique. The recordings of Reinaldo Arenas in this programme are taken from BBC archive, and the documentaries Conducta Impropria and Seres Extravagantes. (Photo: Reinaldo Arenas.

A prison camp called Jaslyk opened in the desert in western Uzbekistan in 1999. Even by the standards of the Uzbek prison system it would become notorious for torture and human rights abuses, including reports of a prisoner being boiled alive. Journalist Muhammad Bekjanov was imprisoned in Jaslyk during the 18 years he spent in Uzbek jails. He speaks to Lucy Burns along with independent human rights observer Acacia Shields.

During the 20th century a British coal miner's son changed the world of art. Henry Moore revolutionised sculpture, altering the way we view the human figure and setting his works in natural landscapes. He became internationally renowned and by the 1970s hundreds of his sculptures could be seen outside government buildings, universities and museums around the world. His daughter, Mary Moore, remembers how initially his work shocked his teachers and art critics.

Hear first hand accounts from the doomed Antarctic expedition which became a legendary story of survival. In 1914, polar explorer Sir Ernest Shackleton led an expedition to become the first to cross the Antarctic continent. But before they could land, their ship, SS Endurance, became trapped in pack ice and sank. Marooned on a floating ice field, Shackleton and his men, embarked on an epic odyssey to reach safety. Alex Last has been listening to BBC archive interviews with the survivors.
