Lost City of Amazonia

What terrible disaster happened to this mysterious human city that it was overtaken by the jungle? One can only guess... While the impressive stone structures still stand, wooden houses have rotted and crumbled and farms have merged with the forest. Let us pay tribute to their work and restore the splendour of this city so that their memory is not lost. Let's just hope we don't suffer the same fate ourselves... --- Your tribe has found ruins of ancient city in Amazon jungle. You have decided to settle there and use it's ruins and irrigation channels for new start of your community. Clearing the trees and bushes is not an easy task, but it will provide you with more than enough wood and considerable quantity of fruit. Can you fight the jungle and bring the city to it's glory again? (Made for Build-a-Map Contest 4)
