Context_1 : The Great Seal of Northern Ireland is the seal used for Northern Ireland. The great seal is in the possession of the Secretary of State for Northern Ireland.

To its north runs the north-Antrim coast, and it is bordered by three other baronies: Dunluce Upper to the south, Cary to the east, and the North East Liberties of Coleraine to the west.

Context_3 : The River Bush (from the Irish: "an Bhuais" ) is an Ulster river in County Antrim, Northern Ireland. The River Bush is 33.5 mi long. The river's source is in the Antrim Hills at 480m. From there the river flows northwest, with a bend at the town of Armoy. It then flows west, passing through Stranocum, and then bends north, passing through Bushmills before reaching the sea at Portballintrae on the North Antrim coast. It flows through a fertile valley devoted to grassland-based agriculture with limited arable cropping. The underlying geology is basalt and the water is slightly alkaline with magnesium making an unusually large contribution to total hardness. The river supports indigenous stocks of Atlantic salmon and brown trout. Saint Columb's Rill, which is a tributary of the river, is the source of water used for distilling Bushmills whiskey. Context_4 : Bushmills is a village on the north coast of County Antrim, Northern Ireland. Bushmills had 1,319 inhabitants in the 2001 Census. It is located 60 mi from Belfast, 11 mi from Ballycastle and 9 mi from Coleraine. The village owes its name to the River Bush and to a large watermill that was built there in the early 17th century. Context_5 : Eilne, also spelt as Eilni, alias Mag nEilne, was a medieval Irish Cruthin petty-kingdom in the over-kingdom of Ulaid. It lay between the River Bann and River Bush, and was centered on Magh nEilne, the "plain of Eilne", spanning north-east County Londonderry and north-west County Antrim, in present-day Northern Ireland. Eilne may represent the name of an original population grouping, though even in the Old Irish period who they were was forgotten. Context_6 : The River Bann (Irish: "an Bhanna" , from "ban-dea", meaning "goddess"; Ulster-Scots: "Bann Wattèr") is the longest river in Northern Ireland, its length, Upper and Lower Bann combined, being 129 km (80 mi). However, the total length of the River Bann, including its path through the 30 km (19 mi) long Lough Neagh is 159 km (99 mi). Another length of the River Bann given is 90 mi. The river winds its way from the southeast corner of Northern Ireland to the northwest coast, pausing in the middle to widen into the enormous Lough Neagh. The River Bann catchment has an area of 5,775 km. The River Bann has a mean discharge rate of 92 m/s. According to C.Michael Hogan, the Bann River Valley is a settlement area for some of the first human arrivals in Ireland after the most recent glacial retreat. The river has played an important part in the industrialisation of the north of Ireland, especially in the linen industry. Today salmon and eel fisheries are the most important economic features of the river. The river is often used as a dividing line between the eastern and western areas of Northern Ireland, often labelled the "Bann divide". Towns, councils and businesses "west of the Bann" are often seen as having less investment and government spending than those to the east. It is also seen as a religious, economic and political divide, with Catholics and Irish nationalists being in the majority to the west, and Ulster Protestants and unionists in the majority to the east; and with the financial and industrial capital of Greater Belfast to the east with the west of the Bann being more agricultural and rural.
