Three years after the devastating fire, Lucy Worsley has exclusive access to the Cathedral of Notre-Dame de Paris at a key turning point of the restoration. Work to rebuild and restore the monument is being ramped up in a bid to meet the ambitious deadline to reopen it to the public in 2024. Scaffolding now fills the interior of the cathedral, giving Lucy and the team unprecedented close-up access to every inch of the structure. Lucy meets scientists, historians and craftspeople working to return the 850-year-old Gothic masterpiece to its former glory.
The fire coated Notre-Dame with tons of toxic lead dust, so specialists are now decontaminating the site. Unique access to the stunning rose windows allows Lucy and the stained-glass historians to uncover the mysteries of these enigmatic 13th-century works of art. An unforeseen legacy of the fire threatens to destroy the remaining vaulting, so the team must develop an ingenious solution to save the stonework. The loss of the roof during the fire reveals hundreds of large iron staples embedded in the stone along the top of the walls. And the incredible task of sourcing and cutting two-thousand perfect oaks gets underway to rebuild the world's most complex medieval timber structure - Notre-Dame's extraordinary roof and spire.

On a dusty highway between Australia's most isolated city and its largest gold pit lies Coolgardie - where the arrival every three months of a new pair of foreign backpackers to work the only bar in town is a keenly anticipated event. Fresh off the plane and lured by the promise of an authentic outback experience, Finnish travellers Lina and Steph find themselves en route to a dot on the map - to pour beers, replenish depleted travel funds, and live amongst the locals. But their working holiday quickly deteriorates into a baptism of fire.
Harangued by their new boss, relentlessly pursued by booze-addled patrons, and prey to the madness and malaise of an environment as claustrophobic as it is isolated - the girls soon realise that to meet expectations out here, they'll need to do more than just serve drinks.

Chronicling events that unfolded over 93 days in 2013 and 2014, this documentary witnesses the formation of a new civil rights movement in Ukraine. What started as peaceful student demonstrations supporting European integration morphed into a full-fledged violent revolution calling for the resignation of the nation's president. The film captures the remarkable mobilization of nearly a million citizens from across the country protesting the corrupt political regime that utilized extreme force against its own people to suppress their demands and freedom of expression.

Scientists and engineers fight to save Notre Dame Cathedral after the 2019 fire. When the roof of Notre Dame Cathedral erupted in flames in April of 2019, firefighters battled for nine gruelling hours to save the historic landmark. Still, Paris came alarmingly close to losing more than 800 years of history. Now engineers are in a different race against time: to rebuild the roof and secure the medieval structure of Notre Dame. Underneath the charred scaffolding and vaulted ceilings of the cathedral, scientists study the components of Notre Dame’s iconic structure to puzzle out how best to repair it.

The architectural design of Beijing's ancient complex of palaces and temples enabled it to survive centuries of earthquakes. The Forbidden City is the world’s biggest and most extravagant palace complex ever built. For five centuries, it was the power center of imperial China and survived wars, revolution, fires, and earthquakes. How did the Ming Emperor’s workforce construct its sprawling array of nearly 1,000 buildings and dozens of temples in a little over a decade?

Physicist Dr Helen Czerski journeys to the extremes of the temperature scale, where the everyday laws of physics break down and a new world of scientific possibilities begins. In the first part, Frozen Solid, Helen reveals how cold has shaped the world around us and why frozen doesn't mean what you think it does. She meets scientists pushing temperature to the limits of cold, driving technologies such as superconductors.
The second part, A Temperature for Life, explores the narrow band of temperature that has led to life on Earth, how life began where hot meets cold and how every living creature depends on temperature for survival. In the last part, Playing with Fire, Helen Czerski explores the science of heat. She reveals how heat is the hidden energy contained within matter with the power to transform it from state to state.
