Buildings, streets, places, roads and position are OpenStreetMap, counted by this site rather than quoted from anywhere. Population, elevation, area and twinning are structured claims on Wikidata (item Q1049641). County population is the Central Statistics Office. Journeys are the National Transport Authority’s published timetable. Every sentence on this page is written from those numbers; none of it is copied from a description of the place.
