This is part of a pirate town that I built a while back. The structure is made mainly out of foam (corchon) and foam board or foam card, then painted...
The layout is as follows... In the front are the boat docks, measured so that a Playmobil pirate ship can dock and unload perfectly. Later, there are two store houses just above the docks. Deeper into the town square are the clock tower and the other building, the open one with the arches, would serve as part of a market. To the left of everything, are part of the ramparts, with a tower, and ports cut out for cannons. The wall is opened on one end to connect to more (unmade) walls and possibly a fort... There is a system of caves in the back, for hiding treasure, etc., but, I unfortunately haven't been able to track down those photos...
