On the 10th of August, 1937, over half of the agricultural land in Simadalen was submerged by the river. The damage to roads and houses was also catastrophic. This was the most destructive flood ever recorded in Hordaland.
The old stone church at Eidfjord has an open position on the terrace at Lægreid. In a diploma from 1310 it transpires that Torgeir on Sponheim donated a gift for the erection of the church in Eidfjord. Thus we can assume that the church was under construction at the time. The elements in the style confirm such a dating.
