The oldest source for the church in Miklibær is from the year 1234 in the Sturlunga Saga, which says from that point on, Kolbeinn ungi (“the young”) Arnórsson had the town because he killed Kálfur Guttormsson and his son Guttormur.

[1][2] Miklibær played a considerable role in the Age of the Sturlungs, especially in the Battle of Örlygsstaðir.

Sturla Sighvatsson stayed there with part of his squad the night before the battle, and his brothers, Kolbeinn and Þórður, fled to Miklibær and sought sanctuary in the church.

After he married another woman in 1777, Solveig developed a mental illness and tried to commit suicide.

[1] Gottskálk Þorvaldsson (1741–1806), father of the sculptor Bertel Thorvaldsen, was the son of a priest from Miklibær.
