The settlements, Watermills and Prodromos separated by a tributary of the river Almopaios or Upper Loudias river, that until recently was the workhorse for many watermills in both villages. The ancient site on the hill 'Goritsa' located between the two settlements. Many important finds from the area (coins, pottery, figurines, etc.) and traditions such as the tombstone of Kassandra and a votive relating to the dedication of an altar.The settlement of the watermill has fortifications while some findings in the area show that there roofs, warehouses, workshops and places of worship.Among the most interesting findings is a head female figurine, a bronze buckle, a relief vessel, an intact oil lamp of the 3rd century eg, an earthen weights with signature, a clay snake cult figurine, some inscribed roof-tiles sections and portion for producing embossed Hellenistic vases.
During excavations were uncovered houses rooms with clay-built or pebbled floors dating to the 3rdcentury AD. The habitation, however, goes back to earlier periods. Already during the Hellenistic period (late 4th-1st century B) there was a remarkable settlement and there have been revealed evidence, dating to late Classical period (4th century BC). It seems therefore that it is an important city in the region in late antiquity.This is something that is found from the first scholar who understood the importance of area N. Papadakis in the article "On the Upper Macedonia", in which ethe researcher xpressly states that there are traces, and pottery pieces dating back to the 5th century BC.However, it is observed that during the First World War, the French army chose this location for a fortress. The army, used materials from the traces previously described by scholar Papadakis.Consequently, there was not rescued a very large part of these relics. Furthermore, most recently in 1994 there was a new outbreak of illicit trade of antiquities.
Another interesting finding is the extensive tumuli cemetery of the Iron Age that has revealed the the corresponding hill 'Goritsa' (west of Prodromos). The gravel mounds have a diameter ranging from 13 to 16.50 m and a height of 1.30 to 1.50 m. Unfortunately they were looted. In the Tomb III was detected an oval tomb, built with 11 pillars and a road to the east with length 1.80 m and width 1.00 m. The two uprights excelled east of the tomb so that could work as a grave marker. The finds, mainly pottery, jewelry and iron weapons, place the use of the cemetery in the 9th century BC.
