While castles are primarily built for defense and usually have thicker walls, palaces typically follow the convention of demonstrating wealth and beauty. Fortresses by definition are large military strongholds that are heavily protected from attack.That's not to say that these often massive structures can't fit into more than one category.Fictional worlds in books, movies, comics, and television can achieve a sense of verisimilitude by making up descriptive names for these imaginary architectural wonders. In fact, some of the iconic castles on this list are basically characters in their own right who gain instant recognition. Giant battles, sieges, weddings, balls, coronations, or escapes would not be the same without these memorable places of refuge. Vote for the greatest.
