 The other possibility is that the "longphort" was situated on the eastern or southern side of the Black Pool, and that Norse settlement began here, expanding northwards and westwards across the Poddle in the late 9th century.Norse houses to the west of these banks all appear to date from the Second Viking Age (917–1170).It is also a possibility that the location of the "longphort" was changed after the destruction of the original settlement in 849.
