Anyway...watchtower required.
Decided to do it in card first to get the proportions right and still be able to have figures on the balcony.
Here's the mock up...

(For the eagle eyed also had a go at stippling the gaming board)
The balcony looks a bit clumsy to allow for the bases, but allows a figure to stand and shoot...but only plastic figures in the card version. The metal figures tip it over! I've bought a flickering flame to put inside for dramatic effect. Beer will dramatically enhance this effect ; )
Plan is to make it in something more substantial and use the template for kids studying Romans as a craft activity : )
Any thoughts on how to do a convincing roof tile in the real thing?
