Andovale Grove
Andovale Grove is a beautiful place built by Aandolaf on the minecraft forums. His idea was a giant valley with vegetation. He used Greek architecture and the palace is very detailed. It took him a couple weeks to build. He  used mcedit and added the trees and valleys and rivers. The  house hanging from the tree is detailed. http://www.planetminecraft.com/project/aandovale-grove/
