There is confusion as this site and the site at Old Carlisle are sometimes both attributed with the name Oleacum. The English Heritage Archive database attibutes this site as Oleacum, and the Old Carlisle site as Maglona. For the two websites on this site, please see: http://www.pastscape.org.uk/hob.aspx?hob_id=46272 and http://roman-britain.co.uk/places/elslack.htm For the site on Maglona, see: http://www.pastscape.org.uk/hob.aspx?hob_id=9942
