I often mention Greenwall on this blog, either as the road of that name or the eponymous house to which it leads. If we're walking around the kirk loop in a clockwise direction, we travel along the former in an easterly direction until we reach the latter.
Local word is that the house is the oldest continually occupied home in Orkney, having being lived in by one family or another since the 17th Century. The house in its current form dates from 1656 (though with later alterations) when Patrick Graham, son of Bishop George Graham, built his mansion. However, an earlier property on the site had been acquired from the Sinclair family in 1646, and history books mention a grange of Greenwall dating to at least the 15th Century.
As is standard for this blog series, here's a map view from 1882:
Really keen readers may recognise the name 'Netherbow' from a Stuff On My Phone post of several years ago.
And here's the property today (well, several days ago, when the sky was much bluer than it is today).
