My son was married last year at this small church at Dunlichity which is about 8 miles from Daviot up a single track road and in the middle of a farming community. Daviot is itself only a small hamlet so you get the picture of the isolated site near lochs and burns and hills. 
Can any bloggers tell me where the smallest church in Britain is located? I vaguely recollect that at Wasdale Head in the Lake District there is also a tiny church.

I live near one outside Frome that sounds very similar to the one you mention up a long farm track. I got out to have a look and within minutes a farmer appeared to ask could he help me (ie. what the hell was I doing there!)
