Belfast Lough in the context of "North Down Borough Council"

Belfast (/ˈbɛlfæst/ , BEL-fast, /-fɑːst/, -⁠fahst; from Irish: Béal Feirste [bʲeːlˠ ˈfʲɛɾˠ(ə)ʃtʲə]) is the capital city and principal port of Northern Ireland, standing on the banks of the River Lagan and connected to the open sea through Belfast Lough and the North Channel. It is the second-largest city in Ireland (after Dublin), with an estimated population of 352,390 in 2024, and its metropolitan area has a population of 671,559.

Occupied since at least the Bronze Age, it was chartered as an English settlement in 1613. The town's early growth thereafter was driven by an influx of Scottish Presbyterians. Their descendants' disaffection with Ireland's Anglican establishment contributed to the rebellion of 1798, and to the union with Great Britain in 1800—later regarded as a key to the town's industrial transformation. When granted city status in 1888, Belfast was the world's largest centre of linen manufacture, and by the 1900s her shipyards were building up to a quarter of total United Kingdom tonnage.

The Inner Seas off the West Coast of Scotland is a marine area designated by the International Hydrographic Organization (IHO). It consists of a number of waterbodies between the Scottish mainland, the Outer Hebrides islands, and the coast of Ireland.

Waterbodies within the Inner Seas include the Minch and Little Minch, the Sound of Harris, the Inner Sound, the Sea of the Hebrides, the Firth of Lorn, the Sound of Jura, the Firth of Clyde, Belfast Lough and the North Channel. The IHO defines the limits of the Inner Seas as follows:

The River Lagan (from Irish Abhainn an Lagáin 'river of the low-lying district'; Ulster Scots: Lagan Wattèr) is a major river in Northern Ireland which runs 53.5 mi (86.1 km) from the Slieve Croob mountain in County Down to Belfast where it enters Belfast Lough, an inlet of the Irish Sea. The Lagan forms much of the border between County Antrim and County Down in the east of Ulster. It rises as a stream near to the summit of Slieve Croob. It runs to Belfast through Dromara, Donaghcloney and Dromore. On the lower slopes of the mountain, it combines with a branch from Legananny Mountain, just opposite Slieve Croob. The river then turns east to Magheralin into a broad plain between the plateaus of Antrim and Down.

The river drains approximately 609 square km of agricultural land and flows to the Stranmillis Weir, from which point on it is estuarine. The catchment consists mainly of enriched agricultural grassland in the upper parts, with the lower section draining urban Belfast and Lisburn. There is one significant tributary, the Ravernet River, and there are several minor tributaries, including the Carryduff River, the River Farset and the Blackstaff River. Work is proceeding to restore a self-sustaining population of Atlantic salmon to the river.

Bangor (/ˈbæŋɡər/ BANG-gər; from Irish Beannchar [ˈbʲaːn̪ˠəxəɾˠ]) is a city in County Down, Northern Ireland, on the southern side of Belfast Lough. It is within the Belfast metropolitan area and is 13 miles (22 km) east of Belfast city centre, to which it is linked by the A2 road and the Belfast–Bangor railway line. The population was 64,596 at the 2021 census. Bangor was granted city status in 2022, becoming Northern Ireland's sixth city.

Bangor Abbey was an important and influential monastery founded in the 6th century by Saint Comgall. Bangor grew during the 17th century Plantation of Ulster, when many Scottish settlers arrived. Today, tourism is important to the local economy, particularly in the summer months, and plans are being made for the long-delayed redevelopment of the seafront; a notable historical building in the city is Bangor Old Custom House. The largest plot of private land in the area, the Clandeboye Estate, which is a few miles from the city centre, belonged to the Marchioness of Dufferin and Ava. Bangor hosts the Royal Ulster and Ballyholme yacht clubs. Bangor Marina is one of the largest in Ireland, and holds Blue Flag status.

Kilroot power station is a fossil fuel power plant on the north shore of Belfast Lough at Kilroot near Carrickfergus in County Antrim, Northern Ireland. The plant currently has a 141 megawatt (MW) capacity from four standby gas turbines and a 10 MW battery energy storage capacity from the Kilroot Advancion Energy Storage Array.

When coal power generation stopped in September 2023, it was the only remaining coal-fired power station operating in Northern Ireland, and it had a 560 megawatt (MW) capacity from dual coal and oil fuelled generators. The station once produced a third of the country's electricity, and was also one of County Antrim's top 100 employers in 2010 (or before).

Blackhead Lighthouse is a listed lighthouse built at the turn of the 20th century, near Whitehead in County Antrim, Northern Ireland. It marks the very northern end of Belfast Lough where it opens out into the North Channel that separates Northern Ireland and Scotland.The active lighthouse is managed by the Commissioners of Irish Lights, where it is named as the Blackhead Antrim Lighthouse to distinguish it from the more modern Blackhead lighthouse in County Clare.

Newtownabbey Borough Council was a Local Authority in County Antrim in Northern Ireland, on the north shore of Belfast Lough just immediately north of Belfast. The Council merged with Antrim Borough Council in April 2015 under local government reform in Northern Ireland to form Antrim and Newtownabbey Borough Council.

Carrickfergus Borough Council was a district council in County Antrim in Northern Ireland. It merged with Ballymena Borough Council and Larne Borough Council in May 2015 under local government reorganisation in Northern Ireland to become Mid and East Antrim Borough Council.

The council was based at Carrickfergus Town Hall and the council administered the town, on the north shore of Belfast Lough, and surrounding area, which extended from Greenisland in the south-west to Whitehead in the east. The borough was 32 square miles (83 km), with a population of just over 39,000.
