Only a few examples approximate a circular form; the majority are only very approximately circular or elliptic. One example atMeisternthal is an exact ellipse with identifiable focal points.The distribution of these structures seems to suggest a spread from the middle Danube (southern Slovakia and western Hungary) towards the west (Lower Austria,Lower Bavaria) along the Danube and to the northwest (Moravia,Bohemia,Saxony-Anhalt) following theElbe. They precede the comparable circularearthwork ortimber enclosures known fromGreat Britain andIreland, constructed much later during c. 3000 to 1000 BC (late Neolithic to Bronze Age).But, by contrast to the long lifetime of the "Megalithic" culture, the time window during which the NeolithicRoundels were in use is surprisingly narrow, lasting only for about 200–300 years (roughly 49th to 47th centuries BC).[3]
The earliest roundel to be described was the one at Krpy (Kropáčova Vrutice), Bohemia, byWoldřich 1886, but it was only with systematic aerial survey in the 1980s and the 1990s that their ubiquity in the region became apparent. Three types have been distinguished:
two semicircular ditches forming a circle and separated by causeways at opposing entrances.
multiple circuits of ditches interrupted with entrances at cardinal or astronomically-oriented points and also having an internal single or double timberpalisade.
The structures are mostly interpreted as having served acultic purpose.Most of them are aligned and seem to have served the function of acalendar (Kalenderbau), in the context ofarchaeoastronomy sometimes dubbed "observatory", with openings aligned with the points sunrise and/or sunset at thesolstices. This is the case with the "gates" or openings of the roundels ofQuenstedt,Goseck andQuedlinburg. The observational determination of the time of solstice would not have served a practical (agricultural) purpose, but could have been used to maintain alunisolar calendar (i.e. knowledge of the date of solstice allows an accurate handling ofintercalary months).[4]
Known Circular Enclosures:
The Lengyel-period rondell of Podhájska, Slovakia, was found in 2022.in Slovakia (Ivan Kuzma 2004): about 50 candidate sites from aerial surveys, not all of which are expected to date to the Neolithic. There are 15 known neolithic (Lengyel) sites (confirmed in 2024[5]). The largest of these are (with outer diameters of more than 100 m): Svodín 2 (140 m), Demandice (120 m), Bajtava (175 m), Podhájska (158 m), Horné Otrokovce (150 m), Podhorany-Mechenice (120 m), Cífer (127 m), Golianovo (210 m), Žitavce (145 m), Hosťovce (250–300 m), Prašník (175 m). Others include: Borovce, Bučany, Golianovo, Kľačany, Milanovce, Nitrianský Hrádok, Ružindol-Borová.
in Hungary: Aszód, Polgár-Csőszhalom, Sé, Vokány, Szemely-Hegyes.
in the Czech Republic (Jaroslav Ridky 2004): 15 known sites, all dated to the lateStroked pottery (Stk IVA). Běhařovice, Borkovany, Bulhary, Krpy, Křepice, Mašovice, Němčičky, Rašovice, Těšetice,[6] Vedrovice, Vinoř roundel near Prague[7]
in Austria (Doneus et al. 2004): 47 known sites with diameters between 40 and 180 m.

Including outliers, the area is somewhat larger, encompassing most ofCentral Europe, stretching over some 1100 km from theDanube-Drava confluence to the lower Rhine (Ruhr area).
