Toponymy
The name Castlefield is a short form of 'field of the castle '. As well as lending its name to the Castlefield area of Manchester, Manchester derived its name from Mamucium which meant "breast-shaped hill" in Celtic. The designation 'The Castle-in-the-field' was in use in the Middle Ages, but eventually came to be abbreviated to Castlefield, as it is in use now.
An alternative to Castlefield has also been in use, i.e. Campfield, with the meaning "field of the fort". It is found in the name of St Matthew's Church, Campfield, and Campfield Market. A further name for the area is Aldport which is Anglo-Saxon and means "the old port" ("port" once had the meaning of "trading place", not necessarily on a waterway, and "the new port" was the main site of medieval Manchester near the confluence of the rivers Irk and Irwell).
