Britain The 2015 Guide

Using 50 years of BBC history archive film, Dr Alice Roberts explores how our views and understanding of Roman Britain have changed and evolved over the decades. Along the way she investigates a diverse range of subjects from the Roman invasion, through Hadrian's Wall, the Vindolanda tablets and the eventual collapse of Roman rule. Drawing on the work of archaeologists and historians throughout the decades, Alice uncovers how and why our views of this much-loved period of our history have forever been in flux.

Janina Ramirez discovers how monasteries shaped all aspects of medieval Britain and created a dazzling array of art, architecture and literature, a story of faith, sacrifice, violence and corruption.

Professor Alice Roberts discovers which are Britain's most popular fresh foods - and uses the latest science to uncover the surprising health benefits of our favourite foods. Last year in Britain we spent over £84 billion on food. With each beep of the till, every item of food we buy is recorded and scrutinised. It produces an extraordinary shopping list - what we're buying most of and spending the most money on. From three billion litres of milk a year to 730 million kilos of bananas, from 520 million kilos of chicken to 1.34 billion kilos of potatoes - the BBC has gained access to the latest information about the fresh foods we load into our supermarket trolleys.

Alice Roberts explores how the public's view of Roman Britain has changed over the decades, examining events from the initial invasion, through to the construction of Hadrian's Wall and the eventual collapse of the empire, drawing on the work of archaeologists and historians and using 50 years of BBC archive footage. With contributions from Charlotte Higgins, Adrian Goldsworthy, Neil Faulkner and Jo Quinn.
