For more than a thousand years the Afon Conwy - the River Conway to the English - provided a military gateway into the heart of North Wales, firstly for the legions of Rome and then the English armies seeking to subdue the people of Wales. In later, more peaceful times, it proved a seemingly impossible barrier to the spread of transport links which sought to open up new and improved communications with Ireland - a barrier that can prove troublesome even today.A Postcard from the Conwy takes the reader on a journey in words and pictures along the entire length of the river and its headwaters, using more than 200 old postcards from the authors' extensive collections. It is a pictorial record of soaring mountains and tranquil lakes, majestic bridges and castles, houses great and small, sailing boats and steamers - all immortalised by past generations of photographers and artists for the benefit of innumerable tourists and travellers.
