Leeds in West Yorkshire is a great commercial city, and its people are very proud of it. Some of the warehouses and factories which made it a wealthy city in the 18th and 19th centuries were destroyed some twenty to thirty years ago, but recently many have been renovated and developed for commercial or residential use. There are now many new buildings, as well as important historical buildings in the city centre. Norwich was one of the chief provincial cities of medieval England. When its walls were constructed (1197-1223), they enclosed almost a square mile, an area as big as that of the City of London. By that time it had become the capital of East Anglia. Its majestic cathedral and the narrow winding streets around it still remind the visitor of those ancient times. Durham. Whatever travellers see or do not see in England, they must see this city, in the north east, just south of Newcastle upon Tyne. No one can forget the sight of its cathedral and castle rising together on a steep hill overlooking a loop in the River Wear, which almost surrounds them. The cathedral itself is one of the great medieval buildings of Europe. Edinburgh has long been the capital of Scotland. Edinburgh Castle is Edinburgh’s principal building, dominating the city, perched on a rock over a hundred metres above sea level. Another important building is the Palace of Holyrood House, founded by James IV around 1500. In between the castle and the palace is the Royal Mile, which was the centre of Edinburgh life before the 17th century and is fascinating to visit now. Liverpool, a port in the north west of England, has a quality that is not found in quite the same way anywhere else in England: the quality of grandeur. Liverpool has this grandeur in its site on the broad Mersey river (more than half a mile wide) with the housesrising above it; in its great dock buildings, its broad streets, and its two enormous cathedrals. Brighton is a seaside resort on the English Channel. Only 50 miles (80km) from London, it offers a good variety of lively entertainment. It is a cheerful place, bustling and crowded in the summer, but alive at every season of the year. Its royal pavilion is a masterpiece of eccentric English architecture.
