Site Comments The Swansea AURN (Automatic Urban and Rural Network) has been affiliated into the UK National Network since 1994 and has been operational ever since. The site was relocated from Castle Gardens in 1995 to Princess Way in the city centre. This site has itself now been decommissioned during August 2006 and relocated to its present location along the A483 Carmarthen road due to redevelopment works within the city centre. The site now has a classification of Roadside. The site picture shows a view of the Swansea AURN looking north towards Cwm Level roundabout. The main city centre shopping area is located approximately a mile and a half to the south this location.
