Welcome to Castlereagh

Castlereagh is a largely urban area bordering Belfast. Unusually, it has no natural borough centre, largely consisting of a series of suburbs of Belfast in the Castlereagh Hills to the south-east of the City with a small rural area to the South of the Borough. The main centres of population are Carryduff, 9.6 km south of Belfast city centre and Dundonald 8 km east of it. The population totals nearly 66,500.

Castlereagh and the city of Kent in Washington in the United States signed up as sister cities partners on 1 August 2000.
