 In the opinion of a number of historians these burials are indicative of a significant early Viking settlement in this region, some three kilometres west of Áth Cliath; it is even possible that the "longphort" mentioned in the annals as being at Duiblinn or Áth Cliath was actually further upstream in this area.A handful of domestic habitations from the same period have also been found at Temple Bar West in the heart of the modern city.Typically these early houses were sunken structures, or Grubenhäuser, with wattle-lined walls, stone or wattle floors, and no hearths.
