The big castle at DL is Sleeping Beauty's castle. At WDW, the big castle is Cinderella's castle and there is a restaurant and now sleeping quarters for lucky guests. Pretty much you just walk through Sleeping Beauty's castle to get into Fantasy Land at DL -- there are some shops -- it is a beautiful castle and does make for a great photo op! I wish they could do more with it like at WDW -- who knows . . .
There is the Storybook Canal Boats ride which show miniature versions of homes of various characters. But as far as castles go -- Sleeping Beauty is the only one at DL who has her own.
