In the heart of the Thames Valley running from London to the West of England, there are numerous towns and historic buildings worth a visit: Blenheim Palace, Oxford, Eton College, Mapledurham and Dorchester to name but a few. Close to London, Windsor Castle, standing in this fertile valley, is of particular interest. A royal residence since the time of William the Conqueror, it has undergone numerous improvements which add to its superb impact. Still used by the royal family, the castle is open to the public who can see the colossal dungeon, the magnificent St. George’s Chapel and the royal apartments, as well as the splendid grounds and royal mausoleum.
