NMRS record no. HY32NW 10 is thought to be a site like that which covered Gurness broch and settlement. The grass-covered stony mound is over a hundred feet across and sixteen high, with several edge-set stones indicating structures below the turf. Gru(d)gar is two fields away and over the road. Ryo is the original appelation and is likely to be either Orcadian ‘roo’ meaning heap of stones or a variant of Grugar (a spindle whorl found on the farm has the name Grudiar/Grudair attached).
