within these walls

A little peice of history:

Civitas, the latin origin of city was used by the Romans to describe the independent states within Gaul, as France was known. Over time it came to represent the principal city in the region. After the Norman conquest there became a link between the term 'cité' and the principal cathederal towns of that period. In Scotland it is this connection that appears to have led to the spread of the term with David I (C12) having used it in the charters of the time for any Bishop's seat. However it is in the early 15th century that it gained its meaning of an important place, , Edinburgh, Glasgow, Perth and Aberdeen all being referred to as a civitas and it is since then that the term has come to prominance over the anglo-saxon burgh.

So if it hadn't been for some Gaul warriors and a few Bishops Ike and Tina Turner could have been singing about "Nutsbush Burgh limits"
