Open Country

Helen Mark visits Coleshill in Oxfordshire to learn about its wartime secrets. In 1940, with fear growing that Britain could be invaded by the German army, the estate became the training headquarters for a secret underground army. Over the next four years, thousands of country men - such as farmers, gamekeepers and foresters - were trained in underground resistance. They lived outwardly ordinary lives, but their job was to spring into action in the event of invasion, disappearing into bunkers buried in the landscape and emerging to disrupt the invading army through sabotage and hand-to-hand combat. Their life expectancy would have been around two weeks.With its quiet countryside location, far from military targets but near good transport links to London, Coleshill was the perfect place for this top-secret training base. High walls around the estate also kept its activities shielded from prying eyes. Even after the war the cloak of secrecy persisted, and today most people have never heard of the role Coleshill played in Britain's wartime history.Helen climbs down into a replica of the original underground operational base, used for training recruits, and finds out what life would have been like for these 'Auxiliary Units' or 'Auxiliers', as they were known. Sworn to secrecy, many never spoke of their experiences and took their knowledge with them to the grave. The feared German invasion never happened, so their services were not called on for real, and in many cases even their families never knew what the Auxiliers had signed up for. Now many people are piecing together their family histories and are keen to find out whether their fathers, grandfathers or uncles may have been part of one of the best-kept secrets of World War II.Produced by Emma Campbell

The landscape of south Wales has been shaped and defined by coal. In this programme, Helen Mark explores the Rhondda valley – finding out about is history and asking what its future may look like, now the heavy industry has gone. She visits a disused railway tunnel which once carried coal from the mines to the port of Swansea, but which has been closed and sealed off for decades. Now a group of enthusiasts is campaigning to re-open the tunnel as a tourist attraction. They have ambitions plans for it to become the longest cycling tunnel in Europe, with hopes that it could also function as an exhibition space, miniature concert hall and even a wedding venue. Helen puts on her safety helmet and is lowered down through a shaft into the tunnel, to see for herself how the structures of the past could take on a new life in the future.Produced by Emma Campbell

Jamie Allan was a celebrated musician and friend of the aristocracy, but also a thief, bigamist, and deserter. Known as "The Dukes Piper", he is the source of many songs and legends in Northumbria. In this programme, folk singer Jez Lowe traces one of these legends across the Rivers Ouse and Nidd, over which Jamie Allan supposedly fled from army conscription to freedom in Scotland. As he crosses the waterways of North Yorkshire, Jez finds out about the life and adventures of this Robin Hood figure from the 18th century, and enjoys some of the music he would have played.Produced by Helen Lennard

Norfolk has around two hundred abandoned villages and more ruined churches than any other county. In this programme, Lawrence D'Silva explores some of them and finds out why there are so many in Norfolk's rural landscapes. He wanders through the grassy outlines of the streets which once made up the medieval village of Godwick, imagines what used to exist in its ghostly outlines, and learns what led to its decline. He finds out how some deserted landscapes are now havens for wildlife, and experiences thousands of rooks and crows coming down to roost at dusk in Buckenham. At East Somerton he finds a ruined church almost swallowed up by the surrounding woodland and hears about the legend of the tree now growing right in the middle of what was once the church's nave. There's even a ruined church which is now part of a private garden. Lawrence meets its owners and finds out how part of Norfolk's history has become part of their everyday lives.Produced by Emma Campbell

From oyster monitoring in Northern Ireland, to beach cleaning in the North East of England, and from wildlife gardens in Felixstowe to tree-planting in Scotland, Helen Mark returns with a new series of Open Country and speaks to some of the many people who give up their time to volunteer on conservation projects. Inspired by the BBC One series 'Wild Isles' which celebrates the natural wonders and wildlife of Britain and Ireland, Helen is on a pontoon in Bangor, County Down to find out why looking after oysters is integral to our seas. She speaks to two people in Bath who have taken on the management of an area of land for the benefit of the community, and hears the inspiring story of how one woman's determination to pick up rubbish on beaches in the North East has blossomed into an organised community project. Produced for BBC Audio in Bristol by Toby Field.

Seahenge is an extraordinary early Bronze Age timber monument which was found on a beach in North Norfolk. Formed of a giant up-turned tree trunk surrounded by wooden posts, it's believed to have been a place where the dead were laid out. It was originally built on land on the edge of saltmarsh, but shifting sea levels meant that it became swamped by the marsh and was then preserved in a layer of peat. Four thousand years later, with further changes to the coastline around The Wash, it emerged once more - as the waves eroded the peat away, revealing the ancient timbers beneath.In this programme, Rose Ferraby traces the story of the monument. She meets the man who originally alerted archaeologists to its presence in the sand at Holme-next-the-Sea, and talks to some of the team who worked on the project to excavate it almost a quarter of a century ago. She goes to see the preserved timbers in the museum at King's Lynn, and reflects on what Seahenge reveals about people's relationships with their landscape in prehistory, and how they have adapted to life on this ever-changing coast.Produced by Emma Campbell

Ruth Sanderson visits the East Neuk of Fife on the east coast of Scotland. "Neuk" is the Scots word for a nook or corner, and Ruth finds plenty of interesting corners to explore as she braves the wind and the cold to meander up the coastline from Elie to Crail. She finds out about the Fife coastal path, discovers some of its many beaches and learns about its seabirds. She also meets a geologist-turned-restaurateur with a professional interest in the area's sealife, who tells her about the importance of fish to the region's trading history. Some of the old fishing villages are now havens for artists: in Crail Ruth visits a family-run pottery which was set up in the 1960s, and discovers how the landscape has inspired three generations of creativity.Produced and presented by Ruth Sanderson

For this week’s Open Country, Helen Mark is in East Lothian in Scotland to revel in the beauty of the winter landscape. On the outskirts of Haddington, wildlife artist Darren Woodhead is ensconced in a hedgerow at dawn. Winter is his favourite time of year to paint; all his painting is done outside, sitting on the ground. He relishes the way in which the elements alter the way water-colours behave on the paper, creating patterns as the paint starts to freeze.Further east on the coast, Helen walks down onto one of the Dunbar beaches known locally as ‘Eye Cave Beach’. Land artist, James Craig, is engaged in the meditative art of stone stacking, at one with his surroundings, racing the rising tide. James organises the annual European Stone Stacking Championships here and tells Helen that his family has had a connection with the stones and the coastline for generations.On her final stop, Helen travels north-west to the sweeping sands of Gullane beach. Emily Hogarth takes inspiration from her daily walks across the wide open bay for her papercut art designs. Her work seeks to make the everyday magical, and she tells Helen there’s nothing like winter in this part of Scotland to heighten her senses. Produced by Beatrice Fenton

Folk musician Johnny Campbell is recording an album of songs from the summits and industrial hotspots of northern England. Jez Lowe joins him at Kinder Scout in Derbyshire to celebrate ninety years since the ‘Right to Roam’ movement began and explore the traditional songs of the Peak District. Jez meets local singer Bella Hardy to hear how her home in Edale has inspired and influenced her work, and writer Roly Smith who can explain the history of Kinder and the 1932 mass trespass. It may be ninety years ago, but for young global folk stars Kate Griffin and Ford Collier of Mishra, the call for a right to roam is still relevant. They have recorded a version of Ewan MacColl’s ‘Manchester Rambler’, a song inspired by the Kinder trespass. Jez meets Kate, Ford, Johnny and Bella to hear how a new generation of musicians are continuing MacColl’s legacy of folk singers fighting for our rights in the countryside. Produced by Helen Lennard
