Context paragraphs:
Scheduled Monuments in Powys: Powys is the largest administrative county in Wales.  With over a quarter of Wales's land area, covering much of the eastern half of the country, it is a county of remote uplands, low population and no coastline.  It was created in more or less its current form in 1974, and is the only one of the large county units created at that time to have been carried forward intact at the 1996 local government re-organisation.  It comprises three historic counties, namely Montgomeryshire, Radnorshire, and most of Brecknockshire.  There are 950 Scheduled monuments within the county.  This is far more than can be sensibly covered in one list, so each of the 3 historic counties is therefore listed separately, and each of these has two lists - one for the prehistoric sites and one for the Roman, medieval and post-medieval sites.

County Tyrone: County Tyrone (from Irish: "Tír Eoghain" , meaning "land of Eoghan" ) is one of the six historic counties of Northern Ireland.  It is also one of the 32 traditional counties of Ireland and lies within the historic province of Ulster.  It is no longer used as an administrative division for local government but retains a strong identity in popular culture.

Ballynahatty, County Down: Ballynahatty is also a townland, in the parish of Drumragh, County Tyrone.

Magherally: Magherally (from Irish: "An Mhachaire Abhlaí" , meaning "apple-tree plain" ) is a civil parish and townland (of 491 acres) in County Down, Northern Ireland.  It is largely situated in the historic barony of Iveagh Lower, Lower Half, with one townland (Tullyhinan) in the barony of Iveagh Lower, Upper Half.  The townland of Magherally contains the parish church.

Setomaa: Setomaa (Estonian: "Setumaa" ; Russian: Сетумаа , ) is a region south of Lake Peipus and inhabited by the Seto people.  The Seto language is a variety of South Estonian.  The historic range of Setomaa is located on territories of present-day Estonia and Russia.  Estonian Setomaa presently consists of lands in Põlva County and Võru County, counties located in southeastern Estonia and bordering Russia.  Pechory has been the historic and cultural centre for the Setos.

Alternative names for Northern Ireland: There are a number of alternative names for Northern Ireland.  Northern Ireland consists of six historic counties of Ireland, and remains part of the United Kingdom following the independence of the other twenty-six counties as the Irish Free State in 1922 (now the Republic of Ireland, officially named "Ireland").  In addition to, and sometimes instead of, its official name, several other names are used for the region.  Significant differences in political views between unionists and Irish nationalists are reflected in the variations of names they use for the region.  A proposal to change Northern Ireland's name was seriously considered by the UK and Northern Ireland Governments in 1949 but in the end the name "Northern Ireland" was retained.

Magheracloone: Magheracloone is a parish in south County Monaghan.  Its name comes from the Irish "Machaire Cluana" which means 'plain of meadow'.  This is a strange name for such a hilly parish; it is derived from its most important place in ancient times; a flat area of land in the townland of Camaghy, on which the sports ground and ancient church of St. Molua were located.  The parish covers 12,952 statute acres in area, making it the largest parish in South Monaghan.  The parish borders three neighbouring counties; Cavan, Louth and Meath.  (Magheracloone is the only parish in Monaghan to border Meath).

Campaign for the North: Campaign for the North is a Think Tank which seeks to address the North-South Divide and establish a Regional Government for the North of England covering the six historic counties of the region.  The Campaign promotes a devo-max settlement and, in doing so, aims to create a Northern Government with tax-raising powers and responsibility for policy areas including economic development, education, health, policing and emergency services.

Westmorland: Westmorland ( ; formerly also spelt "Westmoreland"; even older spellings are "Westmerland" and "Westmereland") is an area of North West England and one of the 39 historic counties of England.  It formed an administrative county from 1889 to 1974, when it was dissolved, after which the whole county was administered by the new administrative county of Cumbria.  In 2013, the Secretary of State for Communities and Local Government, Eric Pickles, formally recognised and acknowledged the continued existence of England's 39 historic counties, including Westmorland.

Moreton-in-Marsh: Moreton-in-Marsh is a town civil parish in northeastern Gloucestershire, England.  The town is located at the crossroads of the Fosse Way Roman road (now the A429) and the A44 and served by Moreton-in-Marsh station on the Cotswold Line.  The parish and environs are relatively flat and low-lying compared with the surrounding Cotswold Hills.  The River Evenlode rises near Batsford, runs around the edge of Moreton and meanders towards Oxford, where it flows into the Thames just east of Eynsham.  Just over 1.5 mi east of Moreton, the Four shire stone marked the boundary of the historic counties of Gloucestershire, Warwickshire, Worcestershire and Oxfordshire, until the re-organisation of the county boundaries in 1931.  Since then it marks the meeting place of Gloucestershire, Warwickshire and Oxfordshire.
