The Neolithic rondels build up a peculiar group of Prehistoric earthworks ranging large territories of Central-Europe during the first third, first half of the 5th millennium BCE. This period is referred to as Late Neolithic in Hungary. These mostly monumental buildings are known under the names of „Mittelneolitische Kreisgrabenanlagen" or Rondel in German, and „circular enclosure" („circular ditched enclosure", „circular ditch system") in English. The classical Late Neolithic rondels occur in Central-Europe roughly between the River Tisza and the River Rhine, in the territory of the Lengyel and related Late Neolithic cultures. The (seeming) uneven range of the sites (e.g. Literski - Nebelsick 2012, Karte 1) results from the different volumes of research conducted in distinct territories as it has recently been proved also by Hungarian research. Due to the aimed research programmes in Western-Hungary the number of the formerly scarce sites has multiplied. There are already nearly thirty Late Neolithic sites with rondels known here, first of all in the territories of Baranya County (Bertók—Gáti 2014), and Zala County (Barna et al. 2016; Barna et al. 2015). The nomination "rondel" can only be used for those Prehistoric earthworks which are constituted by one or more ditch(es), the form of the ground-4. Női szobor töredéke, Sormás-Török-földek. (TGYM) Torso of a female shaped figurine, Sormás-Török-földek. (TGYM) plan is more or less circular, and the ditches are interrupted by nearly symmetrically arranged openings (gates) (Fig. 5). The diameters vary between 30 and 300 metres. The most important structural elements are the (mostly) concentric, pointed ditches, the palisades accompanying the ditches, occasionally earthen rampart and the approx, symmetrically arranged and deliberately oriented gates. One could solely enter the rondel through the earthen bridges running over the 25 I
