Professor Alice Roberts follows a decade-long historical quest to reveal a hidden secret of the famous bluestones of Stonehenge. Using cutting-edge research, a dedicated team of archaeologists led by Professor Mike Parker Pearson have painstakingly compiled evidence to fill in a 400-year gap in our knowledge of the bluestones, and to show that the original stones of Britain’s most iconic monument had a previous life. Alice joins Mike as they put together the final pieces of the puzzle, not just revealing where the stones came from, how they were moved from Wales to England or even who dragged them all the way, but also solving one of the toughest challenges that archaeologists face.

Who built Stonehenge and why? Groundbreaking archaeological digs have revealed major new clues about Britain's enigmatic 5,000-year-old site and the people who constructed it.

“As death, when we come to consider it closely, is the true goal of our existence, I have formed during the last few years such close relationships with this best and truest friend of mankind that death's image is not only no longer terrifying to me, but is indeed very soothing and consoling” - thus said Mozart about death. Mozart died in 1791 and was buried in a mass grave, as standard at the time in Vienna for a person of his social and financial situation. In 2000, 452 of Riga’s deceased — people without relatives, the homeless and the unidentified — were buried at the Jaunciems cemetery. But this film is not about death: it's about Mozart, The Magic Flute, Riga, and love. A short commissioned for the Latvian exhibition at Venice Biennale.

Thundering across the sky on elegant white wings, the Concorde was an instant legend. But behind the glamour of jet setting at Mach 2 were stunning scientific innovations and political intrigue. Fifteen years after Concorde's final flight, this documentary takes you inside the historic international race to develop the first supersonic airliner. Hear stories from those inside the choreographed effort to design and build Concorde in two countries at once - and the crew members who flew her.

Fifty years ago, on Sunday, 2 March 1969, Concorde flew for the first time. Starting from this inaugural flight, the film goes back in time to the origin of the conception of Concorde.

The Channel Tunnel linking Britain with France is one of the seven wonders of the modern world but what did it take to build the longest undersea tunnel ever constructed? We hear from the men and women, who built this engineering marvel. Massive tunnel boring machines gnawed their way through rock and chalk, digging not one tunnel but three; two rail tunnels and a service tunnel. This was a project that would be privately financed; not a penny of public money would be spent on the tunnel. Business would have to put up all the money and take all the risks. This was also a project that was blighted by flood, fire, tragic loss of life and financial bust ups. Today, it stands as an engineering triumph and a testament to what can be achieved when two nations, Britain and France put aside their historic differences and work together.

Real-life drama about why, in a beautiful and quirky rural town, film- maker Jez Lewis' childhood friends are killing themselves.
