Sea Eagle (inn)
The Sea Eagle was a mid-18th century Inverness inn. It was built close to the English garrison in the town, and was atypical of Scottish pubs. Instead it had the height and timbers of many English buildings of the period, rather than the dour, squat look of a typical Scottish one. Its clientele thus mostly consisted of English soldiers. (DWN: The Highlanders (novelisation)) Many of the English perpetrators of Scottish enslavement, like Trask, Soliciter Grey and Perkins frequented the inn's pub.
Polly Wright and the Second Doctor both spent some time in disguise in the place, trying to discover the fate of the Anabelle, a slave ship to which Jamie McCrimmon and Ben Jackson had been taken. (AG: The Highlanders)
Behind the scenes
The Sea Eagle is not named within the surviving audio for The Highlanders. However, the name is prominently used in both the linking narration read by Frazer Hines on the AudioGO release. And it's used prominently in the Target novelisation, where it lends its name to a whole chapter.
