The finest collection of graves from the Viking period in Caithness comes from Reay (NC973650). The earliest recorded Viking grave was discovered in 1912 and comprised a skeleton together with a buckle from a horse bridle. In 1913 a female grave was discovered; finds comprised a pair of oval tortoise brooches, a small bronze buckle, a steatite spindle whorl and iron bridle bit. Further activity in 1920 revealed a rich male grave. The burial, covered with a mound of stones, contained a ringed pin, an iron axe, shield boss, iron sickle and pieces of flint. The finds suggest a date around the 10th century.
