KGA Altruppersdorf could only be surveyed in its preserved western half. From the quite accurately circular remaining part of the inner ditch we can deduce a best-fit central point. This centre does not show any anomaly in the magnetogram, and from exactly this spot, none of the entrances fit a solstice or lunistice. However, from locations within less than 4m, we...
Read MoreThis KGA was surveyed with geomagnetic prospection and was also target of several excavations. It is situated on the shoulder of a ridge and shows three entrances which at first glance show perfect northern and eastern, and less perfect (171°) southern orientation. However, all three entrances can be shown to be oriented downwards in the terrain, while behind the...
Read MoreThe magnetogram shows traces of a single-ditch KGA but no traces of a palisade. The KGA likely had 2 entrances, near 102° (“downward”) and on the opposite side, where two gaps in the strongly eroded ditch can be seen, at 280° (“upward”) and 322°. Any formerly proposed astronomical orientation can be excluded. ...
Read MoreThe KGA shows two entrances towards 165° and 326° which are outside of the solar or lunar ranges, making stellar orientation the only possible astronomical relation. However, the results from the horizon survey contradicted the formerly suspected star-oriented results, but it turned out that the terrain is sloped by about 6° towards 170°, making slope orientation...
Read MoreThe magnetogram of this small KGA shows 3 gaps, where the southwestern gap appears to be due to strong erosion, so only two can be interpreted as entrances. The eastern entrance (89°) fits reasonably well to the equinox sunrise direction, while the opposite entrance near 274.5° misses any significant solar direction (declination 5.3°). Equinox orientation is...
Read MoreThis remarkable triple-ditch KGA has 5 entrances which follow a hexagonal pattern where the northernmost entrance (at azimuth 20°) has been omitted. The entrance at azimuth 265° coincides well with equinox sunset in almost 5 degrees altitude, but other entrances do not offer astronomical explanation. There is also no clear correlation with terrain slope, although...
