"This is Edinburgh."
Translation:Seo Dùn Èideann.
Both actually come from older Cumbric (closely related to Old Welsh, before Irish/Gaelic migration to Scotland) Din Eidyn ‘fort of Eidyn’. Gaelic Dùn Èideann and English/Scots Edinburgh are both adaptation of that older Brittonic name.
Eidyn seems to be the Cumbric name for the region around Edinburgh. See more in Etymology of Edinburgh on Wikipedia.
