What is "maidenkirk"

Maidenkirk (sometimes Kirkmaiden) is a small settlement in Galloway, Scotland, located approximately south of Stranraer.

Until Union with England, Scotland's equivalent of the phrase " Land's End to John o' Groats" was often "John o' Groats to Maidenkirk", as Maidenkirk was traditionally considered the southernmost part of that country. It can be found in the song, The Lady of Kenmure:

From John O' Groats to Maidenkirk You'll never find a truer For loyal faith and dauntless deeds, Than the Lady of Kenmure.
