Colossus construction stages
The Colossus of Rhodes is a Wonder that requires Sulfur to build.
It shows very nicely the different construction phases as progress is made in checkmarking one resource bar after another.
Water Only[]
Like the Lighthouse, the Colossus may be placed in water only. Do not place on land.
Update: And a few Mountain Locations[]
It has been found that the Colossus in addition to the waters around the island may be, if carefully aligned, placed into a limited few mountain locations. One of these locations is the mountain in the back right corner. This is widely considered a bug and not intentional on the part of the designers.
