The worldâs water exists naturally in different forms and locations: in the air, on the surface, below the ground, and in the oceans. Freshwater accounts for only 2.5% of the Earthâs water, and most of it is frozen in glaciers and ice caps.
On Christmas Day, 1066, William the Conqueror was crowned the first Norman king of England, in Westminster Abbey, and the Anglo-Saxon phase of English history came to an end. French became the language of the kingâs court and gradually blended with the Anglo-Saxon tongue to give birth to modern English.
Many Norman castles survive from the reign of the first Norman King of England, William-now known as William the Conqueror but then known as William the Bastard. Among them are the Tower of London, Windsor Castle, Durham Castle and Norwich Castle. Notable examples in Wales are Chepstow and Pembroke.orman Castles were typically built on the highest ground in the area, often adjoined Rivers and overlooking towns and harbours. They often made use of existing sites of Roman or Saxon forts and burhs. If no suitable motte existed then the Normans simply built one-as at Norwich.
