Castles bring up images of knights in armor, but that was only a small part of their history. Beginning in the 9th century as fortified strongholds, castles grew into large residences with thick stone walls, moats, and gates. When times changed, so did the castles, becoming less for defense and more for show and opulence. Castles eventually turned into the wild fantasies of eccentric nobles or nostalgia for an idealized past. Lisa Kent will discuss the history of the castle, from a fortress for defense against invading enemies to fun and fanciful mansions, all of them fascinating and worth a look.
