Circular enclosures [Kreisgrabenanlagen] or rondels have raised the interest of archeologists for more than a century. During the past two decades they received intensified attention in the media and wider public as “solar observatories” or “calendrical monuments”. After conferences at Goseck [2004] and Heldenberg [2005], the time was ripe for another workshop combining recent research with fresh ideas. This took place online in 2022 as part of the research project Constructed Knowledge of Free University Berlin. The present volume contains 21 out of 30 papers presented there. Topics include new hypotheses and research on rondels in general, an overview of the FUB research project, site studies based on excavation, survey, in situ pXRF, experimental reconstruction, and Bayesian modelling at places such as Velm, Hornsburg I, Eggendorf am Walde, Niederleis, Rechnitz, Schletz, Heldenberg [A], Hradec Králové [CZ], Goseck, Kyhna, Quedlinburg I, Ippesheim, Hopferstadt, and in North Rhine-Westphalia [D]. Additionally, there are studies on visual characteristics and orientation patterns of rondels, their aptitude as venues of processions, and on burial customs of the Western Lengyel Culture.weiterlesen
