This revolving millstone was found during excavation work for a private house in St. Ulrich and dates back to the early Iron Age. This type of millstone follows on from the earlier hopper and lever type and therefore has the same function as the typical Mediterranean millstone. However, it has side grooves for inserting wooden levers, which made turning the stones a lot easier.

This typical Mediterranean millstone made from local porphyry dates back to pre-Roman times and was found in various pieces at Col de Flam. Small quantities of grain (barley, oats) were shaken through the hole and milled when coming into contact with a flat, fixed lower stone. The upper stone was turned with a wooden handle, while the lower stone has not been preserved.

This simple nail has U-shaped bends in three places and has one rolled-up and one sharp end. This is evidence that fishing took place in Grödner Bach stream (Ladin: Derjon) during the prehistoric period. The bronze hook was excavated together with other bronze utensils (clasps, nails, button, ring) in an Iron Age dwelling from the 4th to the 2nd century B.C. at Col de Flam.

These two grindstones made of volcanic stone from Col de Flam excavation site were used for milling grain. Grindstones were pushed back and forth across a fixed grinding stone. This spherical grindstone exploded after being heated to a high temperature. This is a sign that a large blaze took place in the house that it was kept in.

A large, shallow, pan-like bowl with two side handles was unearthed during excavation of a floor in a Rhaetian dwelling south of Col de Flam historical farm side. The excavation work was carried out druing the extension of the from from St. Ulrich to St. Jakob and provided the first certain proof of an Iron Age settlement at Col de Flam.

In prehistoric dwellings, large ceramic containers were used to keep foodstuffs in. These coarse clay shards have decorative trims going around them, partly smooth, partly with indentations. The finds come from Rabanserhof in St. Peter at Lajen, the original parish of Gröden. They were unearthed during excavation of a house from the mid Bronze Age (1500 - 1350 B.C.).
