This crude structure was Fidelium set up by it's settlers in it's early days. The former slaves that made up the bulk of the population had little experience setting up improvised structures (their masters prefer to build structures that can last for several centuries with care), though they did have some assistance from the mercenaries and Janissaries in kludging together shelter. A fair bit of effort was expended piling up flat rocks to make half of one wall before rain had forced the builders to go for something that could be set up. In this case this was the sides of larger crates (most of which for Valcas goods) and pallets hammered onto a rough frame of planks and timber and augmented with straw local branches and a wad of waxed paper bags held together with pins. A rain barrel is set aside to collect drinking water. The result of which was a small space enclosed against the wind and most of the rain in which a few items of use can be stored. A basic work table was put up in there by some carpenters. It's a step up from a tent, but not by much. At this early stage many the first wave of ex-slave settlers remember their barracks fondly. Never the less as time passes better dwellings can be contrived.
