The Kettukangas area of prehistoric relics
Located in the Mattilanperä village in Jylhäharju, the Kettukangas area features roughly 100 prehistoric relics that represent five different relic types.
The most noticeable ones are the cairns, of which more than 30 have been discovered. They are mostly situated at an elevation of 57.5–55 metres and, topographically, their dispersion follows the longitudinal direction of the area. The round or elliptic rock piles or rings consist of rocks that measure 10–30 cm in diameter. Many of the cairns are low circular formations, roughly half a metre in height. The tallest ones rise to a height of more than one metre. Quite a few of the cairns feature a round crater-like depression in the middle, which can be either shallow or deep.
Depressions in the ground
The area also features some 30 depressions that have been interpreted as bases of prehistoric dwellings. They are clustered along the longitudinal axis of the ridge at an elevation of 57.5–55 metres. Situated in close proximity to one another, the depressions form lines of oblong or elliptic pits that follow the ancient shoreline. The depth of the pits varies from 0.3–0.8 metres. Many of them are lined on one or more sides by a wall made from stone, gravel or combination thereof.
The original size of the Giant’s Church stone formation near the top of the ridge has been about 30 x 20 metres. The rectangular remains were partially destroyed by gravel extraction and the wall currently stands at approximately 30 cm in height and 3–4 metres in width. The southwest portion of the wall features a gate-like opening and a depression roughly four metres in width. The centre of the Giant’s Church enclosure is fairly even and free of stones, compared to the surrounding area.
Mounds of fire-cracked rocks
The 15 mounds of fire-cracked rocks found in the area form a line that spans along the ancient shoreline to the southeast side of the ridge that lies at a height of 53–54 metres. The round or elliptic mounds vary between 2.8 and 8 metres in diameter and 0.3–1.1 metres in height. At least two of the mounds are supported by a fairly large boulder.
The area also features around ten pit structures that are linked to the low stone embankments formed on the ancient shores by natural forces. The diameter and depth of the crater-like pits vary between 1–3 metres and 0.3–0.5 metres, respectively.
