3D max Castle

This castle I made in this picture that I made using 3D studio max looks complicated, however it was made from nothing but one cylinder and one box.
  What I did was, I created a basic cylinder and then I right clicked on perspective and then clicked Edged Faces, I then went to Modify then turned it into Editable Mesh. After I had turned it into the Editable Mesh I then selected Polygon and selected the top part of the cylinder but skipped one (as if it looked like a dart board when I was done). I then pulled the selected parts of the cylinder up to make it look like a sand castle's tower
