The Fylde peninsula stands between Morecambe Bay, the Bowland Hills and the Irish Sea. Its position means that it's a very windy spot. Windmills have been a feature of the area for hundreds of years, built to grind grain and drain marshy areas in order to turn them into agricultural land. At one point there were over 35 of them on the Fylde coast. Rendered obsolete by the arrival of new technologies - first steam, then electricity - only a few are still standing today. Martha Kearney visits one of the last remaining windmills, Little Marton in Blackpool and also travels inland to discover how some of the impacts of the previous generations' decisions about landscape management are being reversed
