Are castles made of stone?
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.
