Carolyn Quinn has family links to Felixstowe, a place she’s visited frequently over the years, enjoying walks along the Edwardian seafront, soaking up its old world charm. For Open Country she returns to take a closer look at this Suffolk town, including how it’s been shaped by the enormous presence of Felixstowe Port, the largest container port in the UK. She begins her journey with David Gledhill at Felixstowe Museum who gives a quick overview of the richly historic area. From there she walks round the corner to Landguard Nature Reserve, overlooked by the port’s enormous cranes. Ranger, Leonie Washington, shows her the reserve's internationally important habitat of vegetated shingle. It supports species like the incredibly rare Stinking Goosefoot and provides habitat for ground-nesting birds like the ringed plover. Next, Carolyn pops on a hard-hat and enters the Port itself, where Paul Davey shares some facts and figures about this bewilderingly huge place. Then it’s onto the Wildlife Trust’s Trimley Marshes reserve. It was created to replace habitat destroyed when the Port expanded around 30 years ago. Carolyn asks Andrew Excell whether this wetland habitat makes up for the lost mudflats. And finally, the seaside holiday scene: Billy Butlin opened an amusement park here in 1931 and later sub-let it to showman and entrepreneur, Charlie Manning, who renamed it Manning's Amusements. Charlie's grandsons, Charlie Jr and Jonny, still run it but have also established Beach Street, where traders operate out of - what else - repurposed shipping containers. Carolyn meets Jonny and his mother, Sarah, who shares memories of the early days. Note: The parody of the shipping forecast was written by Les Barker and included on the album ‘Guide Cats for the Blind’ created by Clive Lever. Producer: Karen Gregor

Paul Evans explores the rich folklore and natural history of St Melangell church near Llangynog in Powys for a new piece of nature writing. Paul is one of our finest nature writers and in this episode of Open Country he talks us through his creative process, which he describes as "a kind of imaginative hunter-gathering”. Inspired by the ancient yew trees that grow in the churchyard, he listens to their stories, such as the science behind their great age and the legend of Saint Melangell, a nun who fled here from Ireland to avoid an arranged marriage. She protected a hare which was being chased by hounds from a royal hunting party, and was gifted the surrounding Pennant valley by the Prince of Powys who was impressed by her bravery. Here she founded a religious community and became known as the patron saint of hares. Immortal yews, magical hares and the mystic Melangell, there is so much rich material for Paul's next piece of writing, a short essay which he reads at the end of the programme. Interviewees: Reverend Christine Browne, Priest Guardian of St. Melangell's Church; Professor Jane Cartwright of the University of Wales Trinity St David; Dr. Emma Gilmartin of the Woodland Trust; Lottie Glover of Montgomeryshire Wildlife Trust.

As a child, Mary McKeown played hide and seek amongst the Beaghmore Stone Circles in her native County Tyrone. It's a mysterious, mystical site with seven circles, ten rows of stones and twelve cairns, all seemingly carefully aligned. They were found by turf cutters in the 1930s, excavated in the 1960s and carbon dated back to the early Bronze Age. There are many theories about what they were used for - perhaps a burial site, a place for harvest ceremonies, or some sort of lunar or solar calendar. The belief that the stones were connected to celestial events prompted Mary, now working as a tourism officer, to bid for Dark Sky status for Davagh Forest, a short distance away. It's one of the few areas in Northern Ireland unaffected by light pollution. In Irish, 'davagh' means cauldron – the site sits in a natural bowl in the forest protecting it from artificial light from surrounding towns and villages. Davagh became the world's 77th Dark Sky park and the first in Northern Ireland. Mary and her colleagues were also successful in getting funding to build an observatory. Resident astronomer, Barry Lynn, operates a telescope through a retractable roof and projects images of the skies on screens around the park. He says he was first attracted to the area by his interest in archaeoastronomy, the study of how past cultures viewed the skies. He says its fascinating to think that centuries ago, people watched the same moon, sun and stars as we do today. Back at the Beaghmore Stones, Helen is persuaded to join Mary for a barefoot walk inside the circles. Some believe that the 'energy' of the landscape promotes a sense of mental well being. Helen remains unconvinced about this, but enjoys recapturing childhood memories. Produced by Kathleen Carragher

Mary-Ann Ochota joins a group of walkers, riders and horses as in the Scottish Highlands as they follow St Columba’s Way, a pilgrim route from St Andrew’s to Iona. Starting at the village of Killin, eleven people and four horses – Istia, Kirsty, Moy and Sasha - follow the old ways through Glen Lochay and Glen Lyon to the Bridge of Orchy. It's a trip organised by The Big Hoof, a group which promotes adventure and wellbeing through long journeys travelling with horses, on both new routes and ancient ones. Participants join the journey for as long as they want - on foot, horseback or bicycle. Mary-Ann meets the people who have decided to take part in this secular pilgrimage, discovers the healing power of walking with horses and strangers, learns why it’s not about simply riding horses but travelling with them as companions, and hears more about the Venture Trust, the charity the group is raising money for. Produced and presented by Mary-Ann Ochota

The landscape of Dungeness, at the south-eastern tip of England, is an unusual one. In this programme, Helen Mark finds out about stories surrounding sound and light on this peninsula which juts out into the English Channel. She visits the huge concrete "sound mirrors" - built in the 1920s as an early detection system for incoming enemy planes. Their technology became obsolete as aircraft speeds increased and radar was invented. They still stand today, but are now part of a nature reserve. Helen finds out how they worked, and experiences for herself their eerie sound projection abilities. She also learns about the wildlife which now thrives around them. A few miles further south, Helen visits the old lighthouse - one of five lighthouses which Dungeness has had in its time. The area stands on vast ever-shifting banks of shingle, which have expanded seawards over the years, leaving previous lighthouses stranded too far from the sea. The construction of a nuclear power station in the 1950s also obscured the lighthouse then in use, so it was decommissioned in 1960 and is now a tourist attraction. Helen walks up its 169 steps to the top and talks to the current owner, whose father bought it on a whim at an auction. In this programme Helen experiences the distinctive sounds of Dungeness - from the magic of the sound mirrors and the whistle of the tourist steam train to the ever-present crunch and rattle of the shingle underfoot. In this pancake flat landscape, sound and light both seem to move in mysterious ways. Produced by Emma Campbell
