In this special Halloween episode, Greg Jenner is joined by Dr Michael Carter and actor Mathew Baynton to learn all about ghost stories in the European Middle Ages. From the 12th century onwards, medieval Europe produced a huge number of ghost stories, often written in monasteries. But why were monks so interested in ghosts? How were ghost stories related to wider Christian beliefs about death and the afterlife? And what happened to these beliefs with the arrival of the Protestant Reformation? From creepy child ghosts to friendly apparitions via the fires of purgatory, this is a glimpse into the strange, spooky and sometimes sinister side of medieval beliefs.
