Thjodhild's church, Norse Christian church in Qassiarsuk, Greenland

Thjodhild's Church is a reconstructed wooden building with Nordic architectural features including stone foundations and turf-covered walls. The structure demonstrates the construction methods used by the Norse community and sits within a larger archaeological site that includes residential remains.

According to Eirik Raudes saga, Thjodhild had the first church built at Brattahlíð after her son Leiv converted her; C14 dating of churchyard burials points to the late 10th century, with burials beginning in 976. Excavations in the 1960s revealed three successive churches: a turf building, a Romanesque replacement around 1200, and a larger rectangular church after 1300. A copy opened in Qassiarsuk in 2000 for the millennium of Christianity in Greenland.

The churchyard held 144 burials, mostly with heads pointing east, a Christian orientation. Only a few were placed in coffins. South of the church lies a mass grave of twelve adult men, and bundles of bones suggest the ground was reused over a long period, including by visitors from elsewhere.

The site lies in Qassiarsuk, reachable by boat from Narsarsuaq across the Tunulliarfik fjord. The reconstructed turf church of 2000 and the ruins of the later stone church with its churchyard wall stand close together and are walked on foot; the ground is uneven grass. The original turf church measured about 2 by 3 metres.

A single oat pollen grain was found in a grass-turf block from the church wall, the only such find in Greenland from this period. Together with quern stones found at the site, it suggests oats were grown locally. Of the 144 burials in the churchyard, only one death cause could be established: a man with a large knife in the left side of his chest.
