Question: In what country can these castles be found?
Context: Kilchurn Castle is a ruined structure on a rocky peninsula at the northeastern end of Loch Awe, in Argyll and Bute, Scotland.  It was first constructed in the mid-15th century as the base of the Campbells of Glenorchy, who extended both the castle and their territory in the area over the next 150 years.  After the Campbells became Earls of Breadalbane and moved to Taymouth Castle, Kilchurn fell out of use and was in ruins by 1770.  It is now in the care of Historic Environment Scotland and is open to the public in summer. Cathar castles (in French "Châteaux cathares") is a modern term used by the tourism industry (following the example of "Pays Cathare" – Cathar Country) to denote a number of medieval castles of the Languedoc region.  Some had a Cathar connection, in that they offered refuge to dispossessed Cathars in the thirteenth century.  Many of these sites were replaced by new castles built by the victorious French Crusaders and the term is also applied to these fortifications despite having no connection with Cathars.  The fate of many Cathar castles, at least for the early part of the Crusade, is outlined in the contemporary Occitan ""Chanson de la Croisade"", translated into English as the "Song of the Cathar Wars". Castles in Spain were built mainly for defensive purposes.  During the Middle Ages, northern Christian kingdoms had to secure their borders with their Muslim southern neighbours, thus forcing both Christian and Muslim kings to grant border fiefs to their liege noblemen so as to keep and maintain defensive fortresses.  When the Reconquista advanced, those border castles lost their initial purpose, and, as in the rest of medieval Europe, they were used as noble residences and fief-keeps.  However, due to sporadic threats of war, they kept their military purposes, for enemy invasions were common.  In some locations, such as the Basque country, fiefdoms did not exist as such, and noble families could not afford nor did they need huge fortresses, giving rise to many tower houses.  On the other hand, in Muslim Spain many castle-palaces were built: the petty "taifa" kingdoms that arose after the fall of the Caliphate of Córdoba were militarily weak but culturally rich, and every emir or king liked magnificent palaces, of which the Alhambra of Granada is an example.  During the late Middle Ages, Christian kingdoms had secured and enriched themselves well enough to support a more courtly lifestyle, so more residential castles were built, such as the Alcázar of Segovia, which was used as the main residence of the kings of Castile, whereas the Castle of Olite, built in a luxurious gothic style, was the seat of the Kingdom of Navarre's royal court. Anthony Salvin (1799–1881) was an English architect, born in Sunderland Bridge, County Durham.  He trained under John Paterson of Edinburgh, and moved to London in 1821.  His works include new churches, restoration of and additions to existing churches, and various other buildings, including schools.  However, he is mainly noted for his work on existing major buildings, including castles, and for designing new substantial country houses.  The castles on which he worked include Windsor Castle, Norwich Castle, Rockingham Castle, Newark Castle, Warkworth Castle, Muncaster Castle, and Warwick Castle.  He also carried out work on the Tower of London, and on Trinity College, Cambridge, Gonville and Caius College, Cambridge, and University College, Durham.  His new country houses include Mamhead House (his first major project), Scotney Castle, Keele Hall, Thoresby Hall, and Peckforton Castle.  In addition he designed the Observatory for Durham University. Taymouth Castle is situated to the north-east of the village of Kenmore, Perth and Kinross in the Highlands of Scotland, in an estate which encompasses 450 acres.  It lies on the south bank of the River Tay, about a mile from Loch Tay, in the heartland of the Grampian Mountains.  Taymouth is bordered on two sides by mountain ranges, by Loch Tay on the third and by the confluence of the rivers Lyon and Tay on the fourth. This is an incomplete list of châteaus and castles in Belgium.  Both the Dutch word kasteel and the French word château refer both to fortified defensive buildings (castles proper) and to stately aristocratic homes (château, manor houses or country houses).  As a result, it common to see both types of building translated into English as 'castle', although many of them are not castles proper.  Combined with the complication that some aristocratic homes were once intended for defence, here they have not been separated into two groups, and most buildings of both types are labelled as 'castles' in this list. Lincoln Castle is a major castle constructed in Lincoln, England, during the late 11th century by William the Conqueror on the site of a pre-existing Roman fortress.  The castle is unusual in that it has two mottes.  It is only one of two such castles in the country, the other being at Lewes in Sussex.  Lincoln Castle remained in use as a prison and law court into modern times, and is one of the better preserved castles in England; the Crown Courts continue to this day.  It is open to the public as a museum.  Lincoln Castle remains one of the most impressive Norman castles in the United Kingdom.  It is still possible to walk around the immense Norman walls which provide a magnificent view of the castle complex, together with panoramic views of the cathedral, the city, and the surrounding countryside.

The term was used by historian William Douglas Simpson, who described the promontory between the Moray Firth and the North Sea as "the north-eastern knuckle of Scotland".  From west to east, the castles are Dundarg, Pitsligo, Pitullie, Kinnaird, Wine Tower, Cairnbulg, Inverallochy, Lonmay and Rattray.  Although Simpson coined the term, he did not draw any connections between the sites, other than their location. The Dunajec river castles is a chain of thirteen medieval castles (some of which do not exist any longer), built in southern Lesser Poland, along the Dunajec river.  The castles protected the border between the Kingdom of Poland and the Kingdom of Hungary, as well as a very important international merchant route, which went along the Dunajec and the Poprad.  Most of the castles are in ruin now, some of them do not exist any longer.  Their history of most castles dates back to the period known as fragmentation of Poland (early 12th century), when, following the Testament of Bolesław III Wrymouth the country was divided into several provinces.  The Dunajec river castles were located on the territory of two castellanies, Wojnicz and Nowy Sącz, in extreme south of the Seniorate Province.
