According to archaeologists aerial infrared images suggest the existence of a late Iron Age settlement, possibly the largest such find ever in the Åland Islands or all of mainland Finland.
The highest point of Åland Islands: summit of Orrdalsklint, in Saltvik
The aerial imaging highlighted a depression 40 metres deep and 12 metres wide which might have been the site of a massive hall used to host gatherings of ancient Vikings. No other similar find of this size has ever been discovered in the Åland of on the Finnish mainland.
The imaging project followed observations of depressions which resembled the outlines of late Iron Age structures from other parts of Scandinavia. Once the images revealed the outline of the hall, cautious excavation turned up personal ornaments cast in silver and bronze, and which point to the site as an important location in the Viking world.
