I am going to be making a cake for a couple with different tastes, and they only want one cake! When I met with them, she brought pictures from a Martha Stewart cake book, and he brought pictures of medieval architecture! It started off as a simple white cake with some purple (wedding color) flowers. Then we started adding some elements that suggested medieval architecture and then before I knew it the groom turned the whole cake into a castle with gargoyles and everything! I'm not sure the bride was thrilled, but she went along with it.

Anyway, I'm making up a few different sketches that I'll be sharing with them. I want them to be in varying degrees of "medieval-ness". I figure this way they can choose something that they will both be happy with, and in their price range. I came up with a design for a castle, but I need some ideas to incorporate the architecture on a more classic cake. I came up with one, but I'm not real happy with it.

Does anyone have any ideas on how to incorporate a classic wedding cake with purple flowers and medieval influences?

Wow, what a great theme! I'm sure your'll have fun with it! I found a few images, I like the first one best, although theres no turrets or anything perhaps you can add a wall like pattern to the fondant or bc a few gargoils sitting on the edge of the tiers?
The other 2 are really nice but not very 'classic wedding' cakey

Let us know how it turns out!

Since you said gargoyles, I'm assuming it's more Gothic architecture than Medieval. All the old cathedrals have beautiful arches, and I think that would look pretty as a design around the cake. Do round tiers and have the design be arches all the way around with flowers at the base. Each tier can be a different style of arch. You can go as simple as the ogival, and as fancy as the flamboyant arch with tracery. You could have one small gargoyle, or grotesque, placed away from each other on each tier (does that make sense?). I think that would be pretty anyway. Do a search for Gothic arches and you will find tons of pics to help you out.
