These crossbow arrows in various forms were defensive or attack weapons used in the Middle Ages and are often found in the vicinity of fortresses. These three arrowheads, dating back to the late Middle Ages, were found amongst the ruins of Wolkenstein castle.

An iron tip from a crossbow arrow (14th - 15th century) was discovered by chance on the Seiser Alm plateau at Kompatsch. This typical medieval attack and defensive weapon is normally found near fortresses.

A Roman knife made from iron was discovered by chance near Fischburg castle (Ciastel de Gherdëina in the Ladin language). The weapon or tool was probably lost in the forest. Gröden did not seem to be a particularly attractive area for the Romans, neither from a geographical point of view nor as a prospective settlement. 

In 1848, a number of trinkets, iron weapons and work tools were laid down in ritual fashion at the Iron Age cult and burial site at Col de Flam. Tools included axes, picks, knives and a few woodworking tools, such as a gouge. One iron pick has an inscription on its handle.

In 1848, during the ploughing of a field at Untercoldeflam farm, a rich collection of iron weapons and tools, as well as iron and bronze brooches and jewellery, was uncovered. The finds, dating from the 6th to the 2nd century BC, partly come from cremation graves and are partly associated with a burnt offering site.

The central metal component (boss) of a wooden shield from the late Iron Age (6th–2nd century BC) was found at Col de Flam. It served to protect the fist of the person holding the shield. It is an example of Celtic blacksmithing and either indicates the presence of Celtic warriors, probably mercenaries, or local copying of Gallic weapons. The wooden part of the shield has not been preserved.

The famous Iron Age discovery site at Col de Flam contains a number of weapons and tools as well as various objects for adorning the person, which were used in rituals. Alongside bronze bracelets, rings and a bead, there are numerous fastening clasps for clothing made of bronze and iron. They have been dated back to 400 to 15th century B.C. according to their decorative features and shapes.
