Excavations indicate three periods of settlement: • In the first period (10th century BC) the Heunischenburg was constructed as a palisaded fortification. • In the second period (10th century BC) the defences were reinforced with a sandstone wall that probably burned down during a battle. • In the third period (9th century) the Heunischenburg was expanded into a strong hillfort. The northeastern flank was guarded by a 2.6-metre-wide, 3.5-metre-high and 110-metre long wall made of sandstone. This was in turn protected by a 3.5-metre-wide
berm and a shallow
ditch The wall on the inner side of the pincer gateway is only of single-leaf construction. The outer wall either side of the gateway approach on the hillside, was 2 metres wide and continued as a 55-metre-long wooden defensive breastwork. This probably enclosed the entire site. The gateway had a 1-metre-wide portal at the rear with a projecting wooden tower.
Excavations The archaeological dating of the site is based on numerous bronze finds, about 70% of which are weapons. There are also needles, rings, razors, decorative discs, fragments of wrought lead, pieces of swords, lance points and arrowheads. Because many arrowheads were found that had not been deburred, it is suspected that there were times when there was an extremely high consumption of munitions in the garrison. A helmet of the
Urnfield period was found at nearby
Thonberg.
Reconstruction In 1986 and 2000, based on clear evidence, a reconstruction was carried out of a section of wall of the final fortification phase with a
berm in front, the gateway with its wooden tower and the gateway cul-de-sac which extended for some way into the interior of the fort. == References ==
