Finding the largest castle in the world is not as straightforward as it might sound. First, although commonly defined as “a defensive structure built as a residence for a ruler or nobleman” it isn’t always clear what a castle really is. Most people would agree that the Moscow Kremlin is not a castle but how about the fortresses in India and Japan?
Second, what should be used as a measure of size and how to determine this? According to the Guinness Book of World Records, Prague Castle is the biggest castle complex while Wikipedia describes Windsor Castle as the largest inhabited castle.
In this interesting article the author measures the area size of a number of large castles using Google Maps and an KML Area Calculator and comes up with a top 5 list. With this method I went out on a search of my own and found some other large castles including a new number 2.
