evidence: First, since the 1955 ‘annexation’ the UK government has most consistently represented its acts as occupation of a territory res nullius (or a terra nullius or territorium nullius). These deeply colonial concepts have a contested and violent history that I cannot explore here. It is sufficient to note that even based only on the most readily available geographical and historical records concerning Rockall, the factual assertion that in 1955 this was a territory that could be described by any of these concepts is unconvincing. Rockall was known to, and subject to extensive exploitation by Irish, Scottish, Norwegian, Dutch and Baltic fishing and trading communities from at least the 16th century and was possibly visited and recorded by the Irish monk-adventurer St. Brendan as early as the 6th century. The rock has a place in both Irish and Scottish mythologies. In the Irish telling it exists due to exploits of Fionn MacCumhaill, in the Scottish as a harbinger of the end the world.
