 To date, more than two hundred houses have been excavated.Among the few recent discoveries relating to this period are the graves of five young Viking warriors, one of which was found at Ship Street Great about 100 metres to the southwest of the Black Pool, the other four being clustered together on the southeastern shore near South Great George's Street.Radiocarbon analysis suggests that all five died in the 9th century, possibly before the establishment of a Viking "longphort" at Dublin.
