Philomena Cunk is on a festive mission to track down the true meaning of Christmas, and find out exactly what it wants. It's an insightful documentary which takes her on a journey from pagan winter festivals and the nativity story, via 'Sir Charles Dickings', all the way up to today's obsession with Santa. Along the way Philomena will be grilling a variety of experts, trying to expose the truth about Christmas, such as why people still put up with 'brussels sprouts'.

In the middle of the 17th century, Britain was devastated by a civil war that divided the nation into two tribes - the Roundheads and the Cavaliers. In this programme, celebrities and historians reveal that modern Britain is still defined by the battle between the two tribes. The Cavaliers represent a Britain of panache, pleasure and individuality. They are confronted by the Roundheads, who stand for modesty, discipline, equality and state intervention. The ideas which emerged 350 years ago shaped our democracy, civil liberties and constitution. They also create a cultural divide that influences how we live, what we wear and even what we eat and drink. Individuals usually identify with one tribe or the other, but sometimes they need some elements of the enemy's identity.

The Last Sacrifice delves into the real-life 1945 witchcraft killing of Charles Walton—the terrifying event that inspired The Wicker Man and birthed the folk horror genre. This unsettling true-crime interrogation probes into the eerie, enigmatic cultural undercurrents that shaped 1970's folk horror genre, leaving an indelible mark on cinema and public psyche.

Composer Howard Goodall uncovers the surprising and often secret history of the Christmas carol including how, over the centuries, carols have been banned by both church and state.

The legend of King Arthur is one of the most evocative stories in British mythology. We think of the romantic King, with his beautiful wife Guinevere by his side and the trusty sword Excalibur in his hand. The truth, we discover, is very different. The story was written in the medieval period but it was set hundreds of years earlier - in the Dark Ages. The programme finds evidence that a real 6th Century warlord actually did exist, and that many of the most famous chapters of the story - such as the round table, the sword in the stone, Camelot - may well have been inspired by real places and events. Hosted by Richard Harris.
