Here's a tower I completed a month or so ago. I'm more or less pleased with it, although I think I'll do a few things differently next time around. It's constructed of 1/2 inch pink foam cut in circles and stacked. The base is also made of pink foam. The top of the tower is simply larger rings with the inside cut out, and the very top was glued down lightly and then I cut out the unwanted sections. The door is from a MageKnight Dungeons set...The wizard pictured for scale is from Reaper miniatures and was painted by my lovely wife!
The tower is just set on the base and can easily be removed in case I ever just need a flat topped hill or want to set the tower on a different landscape...
