Hi Fiona. Late comment on this but I only just discovered that Brora is derived from a Norse name meaning “river with a bridge”. Given that Norse was being superseded by Gaelic by the 10th/11th century and names need some time to stick, this probably gives more support for bridges existing in the north of Scotland at the time of Sueno’s Stone’s creation.
