Wales has myriad towns and villages with seemingly unpronounceable names, its own language, an ancient form of Celtic, its own prince, Charles, narrow-gauge steam railways that puff contentedly through glorious scenery, and more castles per square mile than anywhere else in Europe. And at journey's end there is bound to be a steaming cuppa to be enjoyed with bara brith, a scrumptious currant bread. As the signs say, Croeso i Cymru—Welcome to Wales.
