A multidisciplinary historic landscape, buildings and materials study is presented, which situates the construction of Castle Roy within the wider physical and cultural environment of medieval Grampian Scotland. The paper highlights that the castle has been constructed close to an ecotone between distinctive upland and mountain biomes, before considering previous evidence relating to the building and its administrative role in the medieval period. A study of the surviving structure and its component materials is then presented, which includes petrographic, archaeobotanical and radiocarbon analysis of a well-distributed assemblage of mortar fragments, in comparison with various potential source materials from the surrounding environment. Informed by these analyses, Bayesian techniques are employed to generate estimates for the constructional chronology of the upstanding building, before reconsidering the history of the lordship and the location of the castle relative to other buildings across the region. Presenting the first independent dating evidence relating to the construction of this culturally significant building, the study ultimately confirms that Castle Roy was probably constructed in the late 12th to early 13th century at the administrative centre of the surrounding lordship and parish.

提出了一个多学科的历史景观，建筑和材料研究，将罗伊城堡的建造置于中世纪格兰屏苏格兰更广阔的自然和文化环境中。该论文强调，在考虑到有关该建筑及其在中世纪时期的行政作用的先前证据之前，该城堡的建造接近于独特的山地生物群落之间的过渡带。然后，对幸存的结构及其组成材料进行了研究，其中包括对分布均匀的灰浆碎片集合的岩石学，古植物学和放射性碳分析，并与周围环境中的各种潜在来源进行了比较。根据这些分析，在重新考虑领主的历史以及城堡相对于该地区其他建筑物的位置之前，先采用贝叶斯技术对直立建筑物的建造年代进行估算。这项研究提供了有关这座具有文化意义的建筑物的建造的第一个独立的约会证据，最终证实了罗伊城堡可能是在12世纪末至13世纪初在周围的领主和教区的行政中心建造的。
