A Late Medieval motte‐and‐bailey settlement in a lowland river valley landscape of Central Poland

Abstract

AbstractThe Rozprza motte‐and‐bailey residence in Central Poland was inhabited from the third decade of the 14th century up to the 15th century A.D. and functioned as a seat of a noble family. It was situated in the place occupied previously by an Early Medieval open settlement and a later ring‐fort. The motte was constructed on the river terrace remnant adjoining a strongly expanding flood plain in the central part of the mid‐Luciąża River valley. The immediate surroundings of the stronghold were studied by means of archaeological excavations, detailed geological mapping (hand‐auger transects and trenching), and large‐scale aerial photography, as well as geochemical and geophysical (magnetic gradiometry and soil electrical resistance) prospection. All the results have been integrated within a GIS and supported by a set of 14C dates that allow for a detailed geomorphological reconstruction of the stronghold situation, including former river patterns, the local flood plain development, and the history of the Medieval fortress site with its moats. Our research provides insights into the late Holocene evolution of a small river valley and confirms the favorable conditions for the location of the motte on a terrace remnant protected by the system of moats and surrounding paleochannels and swampy areas within the valley floor.
