Inverkeithing is on the site of a small river called the Keithing Burn, part of which can still be seen on the northern shore of the Firth (estuary) of Forth (river) north of Edinburgh with settlement extending back beyond 1000 years. http://www.scottishchurches.org.uk/sites/site/id/2430/name/St.+Peter%27s+Parish+Church+Inverkeithing+Fife

It has had provided varied sources of employment apart from those required to maintain a small community, including agriculture, ship building, ship breaking, paper making, quarrying, housing workers working on bridges over the river, scrap metal recycling and now it seems to be somewhat of a dormitory suburb for Edinburgh along with long stay parking for drive and ride commuters.
