The original building dates to the thirteenth century when
it was owned by the MacSweens. In 1262, King Alexander III granted the castle
and its lands to Walter Stewart, the Earl of Menteith. It is believed that
Robert the Bruce landed at Lochranza in 1306 on his return from Ireland to
claim the Scottish throne.[2] By 1371, the castle has become the property of
Robert II. It is thought that at this time it was used as a royal hunting
lodge.
