So this city is commonly named Kilkenny, this is for fane or cell of Canice. Canicopolis is another name for Kilkenny City

Kilkenny City (Ireland) is seated on the river Nore. This website tells the story of Green’s Bridge, one of three city bridges spanning the Nore. It also tells the story of Anglo-Irish philosopher George Berkeley (1685-1753) who was born and educated in Kilkenny and who died 13 years before Green's Bridge was built.

So this city is commonly named Kilkenny, this is for fane or cell of Canice (as Miraeus rightly halt it), but may, since the recent accession of honours and privileges conferred on it royal favour, be aptly styled, in composite diction, Canicopolis. Seated on the river Nore, which flows beneath two marble bridges distant from each other about two furlongs, its greatest length is from north to south. On the north stands boldly forth the large and magnificent cathedral church sacred to St. Canice, the abbot; southwards, and verging towards the east, rises the castle, or rather fortress guarded by many castles and bulwarks.
