I was wondering if the rule for barracks is 'has an empty edge' or 'on the outer edge of the city' and it appears that it's the latter, which would make sense for the idea of the barracks defending the city.
I just had a game with a barracks with one edge on a 'lake' (a completely surrounded hole in the city) and it didn't count.
