Hvalsey Church Close to the town of Qaqortoq in South Greenland lie the ruins of Hvalsey Church, which are Greenlands biggest and best-preserved ruins from the Viking period. The church was built of stone in the 14th century and measures 16 x 7 metres (52.5 x 22.75 feet). It is situated next to the ruins of a farm complex which is also from the Viking period, and thus provides a good insight into how the Norse settlers lived.
In the Vaticans annals in Rome there is a historically significant account of a wedding between Thorstein Olafsson and Sigrid Bjørnsdatter in Hvalsey Church in 1408. The records also show that the last wedding guests traveled back to Iceland in 1410. This wedding is the last written evidence of the Viking settlers in Greenland.
