Wanderlust World Wanderlust World Northern Ireland is the only part of the United Kingdom that shares a land border with the Republic of Ireland.
Border: 499 km (310 mi) — meanders through fields, rivers, lakes, and towns. Status: One of the UK's four constituent countries (with England, Scotland, Wales). Capital: Belfast. Population: ~1.9M. Created: 1921 (Government of Ireland Act 1920) — partition of Ireland.
The border became the UK-EU land frontier. The Northern Ireland Protocol / Windsor Framework keeps NI aligned with EU single market for goods, avoiding a "hard border" (infrastructure/checks) on the island of Ireland — preserving the Good Friday Agreement (1998) peace settlement. Customs checks occur at NI ports (Belfast, Larne, Warrenpoint) for GB-NI goods.
North/South Ministerial Council, all-island bodies (Tourism Ireland, Waterways Ireland, Food Safety Promotion Board), shared energy, health, education initiatives. Daily cross-border commuters: ~30,000.
