William The Conqueror. Aka William of Normandy.
The stone castle was invented and first built by King William I of England (William the conqueror). He built stone castles a few years after he built Motte and Bailey castles in 1066.
Stone keep castles were built in 11th - 13th centuries.
In 1066 by the Normans
Stone or square keep castles were first built in Medieval England by William the Conqueror. Stone keep castles were the natural extension of motte and bailey castles. Motte and bailey castles were only temporary features (though many mottes exist to this day) while stone keep castles were built to last.

All castles that exist today are made from stone because stone lasts for a long time. In total there were three types of castles: Stone Keep castles (Stone castles), Motte and Bailey castles and Concentric castles. The Stone Keep castles were made out of stone along with the Concentric Castles and still stand to this day as great monuments. The Motte and Bailey castles, however were made out of wood and have all rotted away to leave none left standing today.
No one really knows the exact date someone created a castle but obviously they were needed to keep towns safe so to answer your question the Normans invented building castles first by using wood and timber and then even after their the Norman invasion of Britain in 1066 they were still using wood and timber to create castles and then through necessity turned to stone castles.
Stone castles were built in 1277 and usually had more that one wall, the inner wall being higher than the outer ones.
They were built in the year 1172
There is no particular year, but most castles had fires to keep warm. For more information on life in castles read this:http://www.castles.org/Kids_Section/Castle_Story/inside.htm
