During a preventive archaeological excavation in the historical centre of Brussels (Belgium), the waterlogged remains of a 13th century AD sunken byre (potstal) were discovered. The exceptional preservation instigated a multiproxy approach, including micro-archaeology, micromorphology, phytolith and parasite analysis on thin sections, palynology and the study of plant macroremains on the fill of the structure. Beyond detailing the content and multiple origins of the fill (including excremental waste and urines, fodder and bedding material, plaggen and/or soil sods, household and construction waste), this study also provides detailed insights into foddering customs, hygienic conditions within the stable, and the health status of the animals kept. Moreover, historians claim the importance of an agro-pastoral system where animals were kept in stables over winter as part of the explanation for cultivating new and less rich soils in high medieval times. The intensive study of high medieval cultivated fields in the historical centre of Brussels indeed shows that they have intensively been amended. So aside from documenting husbandry practices, this study also informs about late medieval farming practices in Brussels, more specifically the need to collect substantial amounts of manure to add as fertiliser onto cultivated poor sandy soils.
