Within the visible earthen bank, he discovered the remains of a wall, which he described as a murus gallicus according to Julius Caesar's description of such structures.

Due to the presence of the airfield, Manching was the target of multiple bombing raids during World War II, causing further destruction of archaeological evidence.

The increasing degree of exploration does, however, coincide with a progressive destruction of the site, as much of the new excavations take place to retrieve information before areas are built on.

It was also near the meeting of the rivers Paar and Danube, giving access to navigation of the latter, further increasing the potential for long-distance trade.

[citation needed] It seems more likely that the rectangular parcels represent areas of specialised function, including aspects like agriculture, craft production and cult.

Only the central area, right between the east gate and the assumed western one, was placed on relatively dry alluvial soils and most densely settled.

The exact reasons for its construction are not known, but apart from a potential threat to the settlement, aspects of prestige may also have played an important role.

Manching appears to be the only known case where murus gallicus (a mostly western Celtic phenomenon) and Pfostenschlitzmauer (common further east) occur in a single site.

It was a Zangentor, i.e. the wall protruded on both sides in front of the actual entrance, thus making it more defensible, as well as more imposing.

This gate was destroyed by fire in 80 BC, its ruins were never cleared, suggesting that the road which it had served was out of use by that time.

An enormous amount of animal bones indicates intense husbandry; perhaps Manching also served as a supra-regional livestock mart.

Products included a variety of specialised tools, clearly indicating a lively craft tradition.

Finds like Baltic amber and Mediterranean wine amphorae show that Manching was part of trade networks spanning all of Europe.

A local system of coinage, including small silver coins (quinarii) and impure bronze ones served mainly internal trade.

External trade relied on coins of gold and (from the early 1st century BC onwards) silver.

The "Altenfeld" excavation revealed evidence for the extensive reuse (recycling) of scrap metal, the reasons for which remain unknown.

Along with a cemetery (see below), this complex appears to represent the earliest activity on the site, suggesting that the settlement developed around them.

Deposits of weaponry, horse trapping and parts of cauldrons, a paved plaza and a large amount of bones from human infants and children indicate the cult use of the area.

It used to be commonly assumed that the Roman occupation of Southern Germany entailed the violent destruction of the Manching settlement.

However, a conquest or complete destruction of the site is considered unlikely today, although Manching may have been involved in some military conflict connected to the migrations of the Cimbri and Teutoni, c. 120 BC.

The reason for the final demise of the oppidum is now seen in the collapse of Celtic economic systems caused by Gaius Julius Caesar's conquest of Gaul.

Manching apparently underwent a long-term loss of population, leading to the abandonment of much of the settled area and the dilapidation of its walls, which could not be maintained any more.

By the time of the Roman arrival around 15 BC, ruins of the imposing walls were all that remained of a city that had flourished a century earlier.

Here, as generally in southern Germany, the number of individuals represented by bone material from the 4th to 2nd century is relatively small compared to the assumed populations of settlements.

Three small bronze rings indicate that it was originally stored in a container made of some organic material.

Four suspects were caught in 2023; melted gold was found in the possession of one of them, which is believed to be a smaller part of the treasure.

When a castrum (a fort) was constructed in the mid-1st century, nearby Oberstimm hill was chosen as its location, probably because the bed of the Danube had moved away from the Manching site.
