Tingwall and Law Ting Holm in Shetland, Dingwall in Easter Ross, and Tynwald on the Isle of Man. Women enjoyed a relatively high status during the Viking Age, possibly due to the high degree of mobility in society. There is little knowledge of their role in the Scandinavian colonies of Scotland although the indirect evidence of graves during the pagan and Christian periods suggests roles similar to those held elsewhere. Amongst the best known figures are Gormflaith ingen Murchada, Gunnhild Gormsdóttir, Aud the Deep-Minded and Ingibjörg, the daughter of Earl Hakon Paulsson and wife of King Olaf Godredsson. The Norse legacy of art and architecture is limited. The Christchurch at Brough of Birsay, now reduced, was the early seat of the Bishops of Orkney. St. Magnus Cathedral, Kirkwall is peerless as an example of Norse-era construction in Scotland and St. Magnus Church, on Egilsay retains its round tower. The iconic Lewis chessmen are the best-known treasure trove and numerous finds of grave goods, including brooches and weaponry such as the Scar boat burial, are well documented. There is growing evidence of the importance of trade and commerce. Data from the Outer Hebrides suggests that pigs were a more important aspect of Viking farming than prior to that time, that red deer numbers may have been controlled rather than the species simply being subject to hunting, that herring fishing became an important commercial consideration and that trade with centres to the south such as Dublin and Bristol may have been important. Coins found at Bornais and Cille Pheadair were produced in Norway, Westphalia, and England, although there were none from Scotland. Ivory from Greenland was also found there. Present day influence Norse and Viking colonisations and settlements have made an impression on peripheral Scotland, the evidence for which can be found in place names, language, genetics and other aspects of cultural heritage. The Scandinavian influence in Scotland was probably at its height in the mid-11th century during the time of Thorfinn Sigurdsson, who attempted to create a single political and ecclesiastical domain stretching from Shetland to Man. The Suðreyjar have a total land area of approximately . Caithness and Sutherland have a combined area of and the permanent Scandinavian holdings in Scotland at that time must therefore have been at minimum between a fifth and a quarter of the land area of modern Scotland. The Viking invasions may have inadvertently played
