Trelleborg is a collective name for six Viking ring castles, located in Denmark and the southern part of modern Sweden. Five of them have been dated to the reign of the Harold Bluetooth of Denmark (d. 986). The fort in Borgeby has been dated to the vicinity of 1000 AD, so it is possible that it too, was built by the same king. The name Viking is a borrowed word from the native Scandinavian term for the Norse warriors who raided the coasts of Scandinavia, the British Isles, and other parts of Europe from the late 8th century to the 11th century. ...

Comparisons of the different ring castles

The ring castles and the contemporary bridge over Ravning Enge/Vejle Å (Vejle river) — together with minor bridges erected on Zealand (Bakkendrop bridge between Gørlev Tissø and Risby bridge by Præstø) and Lolland (over Flintinge river) — differ clearly from others from the Viking Age. Unlike other ring castles from the period the ring castles which follow the Trelleborg model are constructed after a strictly geometrical plan and measured with the Roman foot.

In spite of searches no real parallels have been found in the rest of Europe. On the coasts of the Netherlands and Belgium there are ring castles with certain points of resemblance and on the island Walcheren there are the remnants of a castle with gateways in the four points of the compass, combined with streets. Trelleborg (Zealand) and Fyrkat are dendrochronologically dated to 980 and the remainder have been carbon-14 dated to about the same time. Around 974 the Danish Viking king Harald Bluetooth(Harald Blåtand) lost the Danevirke and parts of Southern Jutland to the Germans. The whole complex of castles, bridges and roads which were built around 980 as a small part of a extensive defence work, are presumed to be Harald’s work.
