Construction materials and building techniques – Comparing anthropogenic sediments of three Middle Bronze Age sites from Hungary

This paper compares various ‘earthen’ construction materials and building techniques from three Middle Bronze Age tell (multi-layered settlement) sites in Hungary: Százhalombatta-Földvár, Kakucs-Turján (Vatya material culture) and Borsodivánka-Marhajárás-Nagyhalom (Otomani-Füzesabony Cultural Circle (OFCC)). It employs microscopic analyses – archaeological soil micromorphology and phytolith analysis within thin sections – to examine floor, wall and fire installation materials at a high resolution. The term ‘earthen construction materials’ is used in archaeology extensively to refer to anything from soils to sediments that sometimes lack proper classification or terminology. Through a closer look at the types of materials used at the three analysed sites, we describe more clearly what comprises ‘earthen’ construction materials. Using this data, we then employ a chaîne opératoire approach to think through various stages in the sourcing and preparation of building materials. In analysing this, the paper makes visible the decisions by Bronze Age builders and discusses their possible reasons, which include environmental conditions and socially learned practices. Further, by comparing three contemporary sites within a micro-landscape, our analysis highlights that even small variations in the environment and therefore the available raw materials impact building materials and techniques, and that different groups of people can make different decisions even when facing similar environments.
