They discoverede there was a fireplace under the foundations dating from the age between 120 BC and 80 AD. There may have been a prehistoric pagan site of worship on the church site. Archeologists also found 804 coins under the choir floor. While many originate from Norway, some are from Germany, Denmark, and Sweden. Most of the coins date from the Middle Ages, the oldest is from 1130.
