In 1957, preliminary investigations revealed a major Late Neolithic settlement mound, which also happened to be the northernmost tell settlement on the Great Hungarian Plain. Although the trial was limited to a small trench, the several meters thick deposits yielded exciting finds and several richly furnished burials. The brief preliminary report and the various references to the excavation made it quite obvious that the tell was one of the key sites of the Hungarian Neolithic and thus the full publication of the tell and its finds was, quite understandably, eagerly awaited by prehistorians. Investigations resumed in 1989 as part of the excavations preceding the construction of the M3 motorway. This excavation was preceded by various geophysical surveys and palaeoenvironmental sampling in order to reconstruct the settlement's one-time environment and to determine the exact date of its occupation. However, until the results of the new excavation are published in detail, this monograph will be the single available study on the Polgar-Csoszhalom site, the eponymous site of a Late Neolithic culture."
