Storeys: 6

This castle took a couple of hours to build the main structure but easily a few days to finish off the decorations.
I hope you enjoyed it and if you want to build something similar you may need to find a server with nonstandard settings that includes maximum castle height 6 storeys. The default maximum castle height is 3 storeys. Better yet, join the server I've made this castle on and say hi! Make sure your server search filter for Clan Size is set to "Any" and search for the server name above.
