There have been several "Winsor Castles" built on the same site. the original was built by William the Conquerer and was probably fairly makeshift as it was built on a heap of chalk and probably took the form of a mott and bailey castle. Later versions including the one you see today are stone built.
Motte and Bailey castles were built in the 11th century just after King William I (Willilam the conqueror) first took over Britain in 1066. Motte and Bailey castles were made out of wood. They were mainley built because they were cheap and light so they were easy to build. They were later replaced by Stone keep castles (Stone castles) because Stone castles were stronger, wouldn't rot within a few years, wouldn't burn etc...
