LLANFAIR : St Mary's Church
The Welsh "Llan" originally meant "an enclosed piece of land", which came to mean "parish", and, by association, "church" over time. Mostly it is followed by the name of a saint, in this particular instance St Mary. You have probably noticed many, many places in Wales begin with "Llan", as do quite a number on Ynys Môn.
