Should we save the beautiful or the useful? Chris Jackson sets out to investigate how we decide which of our historic buildings should be preserved for future generations. Gayle Mill in Wensleydale, a finalist in the 2004 Restoration series, shows what can be done to bring history back to life. In a journey across the North, Chris assesses the plans for Dunston Staithes in Gateshead, The Old Station Goods Yard in Hexham, the Union Bridge in Horncliffe, and Kirklinton Hall in Cumbria.
