Knights' Castle Birthday Cake

This birthday Cake was made for a 6 year old boy called Andreas. 
Happy Birthday Andrea!!
The idea came from Debbie Browns' Book "50 Easy Party Cakes", which I find a very good source for birthday cake ideas.  The design was a bit different than mine. For a birthday cake in this size I think my version looks better...! The main castle had a diameter of 21cm x 21cm and the height was about 16cm.
My kids were very excited with this birthday cake, so I think I will make something similar for my boys when they will have their birthday party.
The cake was made with butter, cacao, powder sugar, eggs, biscuits, vanilla essence and brandy.  The castle towers were made with round cardboard covered with fondant.
The flag was made with gumpaste.
