Context paragraphs:
Norwich Castle: Norwich Castle is a medieval royal fortification in the city of Norwich, in the English county of Norfolk.  It was founded in the aftermath of the Norman conquest of England when William the Conqueror (1066–1087) ordered its construction because he wished to have a fortified place in the important city of Norwich.  It proved to be his only castle in East Anglia.  It is one of the Norwich 12 heritage sites.  In 1894 the 'Norwich Museum' moved to Norwich Castle and it has been a museum ever since.  It is now known as Norwich Castle Museum & Art Gallery, and holds significant objects from the region, especially archaeological finds and natural history specimens.

Torà: Torà (] ; Spanish: "Torá" , ] , ] ) is a town and municipality in the North East of the "comarca" (county) of Segarra, in the province of Lleida, Catalonia, Spain.  The urban structure of the center has retained most of its original design, with narrow, twisting streets and blocks formed by rows of attached buildings.  The Medieval town grew around a castle or fortified place ("Thoranum castrum").  A particular trait of the fortified origin of the town is the presence of a number of portals to allow several streets their pass through defensive barriers formed by the rows of buildings of the town and its walls.  Torà is some 10 kilometers northeast from the more populated Guissona (6,145 inhabitants in 2010), a neighbor town that has experienced an important economic development in the last half century (mainly due to meat production and generation of a meat packing industry) parallel to an unprecedented demographic growth sped up in the recent years (from 3,060 inhabitants in 1998 to 6,145 in 2010).

Borremose: Borremose is a raised bog in central Himmerland, Denmark south east of the town of Aars.  The name translates directly as 'Borre'-bog, where 'Borre' might well be a derivation of the old word "burgh" meaning fortified place, as seen in many other place-names.

Old English: Old English ("Ænglisc, Anglisc, Englisc" ) or Anglo-Saxon is the earliest historical form of the English language, spoken in England and southern and eastern Scotland in the early Middle Ages.  It was brought to Great Britain by Anglo-Saxon settlers probably in the mid 5th century, and the first Old English literary works date from the mid-7th century.  After the Norman Conquest of 1066, English was replaced, for a time, as the language of the upper classes by Anglo-Norman, a relative of French.  This is regarded as marking the end of the Old English era, as during this period the English language was heavily influenced by Anglo-Norman, developing into a phase known now as Middle English.

Chesters Hill Fort: Chesters Hill Fort is an Iron Age hill fort in East Lothian, Scotland.  It lies one mile south of Drem, 1.5 miles east of Ballencrieff Castle, 2.5 miles north of Haddington, and 2 miles west of Athelstaneford.  The name "Chesters" comes from Latin "castra", a fortified place.

Melbury Bubb: Melbury Bubb is a small village and civil parish in the county of Dorset in South West England, situated in the West Dorset administrative district approximately 7 mi south of the town of Sherborne.  It is sited on Cornbrash limestone beneath the chalk hills of the Dorset Downs.  The A37 trunk road between Dorchester and Bristol passes about 0.5 mi to the west, on the other side of Bubb Down Hill.  This hill used to be the site of a beacon.  The first half of the village name derives from "maele" and "burh"—Old English for "multi-coloured" and "fortified place"—and the second half is a manorial name which derives either from a Saxon resident named 'Bubba' or from medieval lords of the manor.  Dorset County Council's latest (2013) estimate of the parish population is 40.

Aornos: Aornos (Ancient Greek: Ἄορνος ) was the Ancient Greek name for the site of Alexander the Great's last siege: "the climax to Alexander's career as the greatest besieger in history" according to Robin Lane Fox, a biographer of Alexander.  The siege took place in April 326 BC, at a mountain site located in modern Pakistan.  Aornos offered the last threat to Alexander's supply line, which stretched, dangerously vulnerable, over the Hindu Kush back to Balkh, though Arrian credits Alexander's heroic desire to outdo his kinsman Heracles, who allegedly had proved unable to take a fort that the Macedonians called Ἄορνος "Aornos" (according to Arrian and Diodorus; "Aornis" according to Curtius; elsewhere "Aornus"): meaning "birdless" in Greek.  According to one theory, the name is a corruption of an Indo-Iranian word, such as *awarana "fortified place".  According to Arrian, the rock had a flat summit well supplied with natural springs and wide enough to grow crops: it could not be starved to submission.  Neighboring tribesmen who surrendered to Alexander offered to lead him to the best point of access.

Clare Camp: Within the boundaries of Clare Parish lies what appears to be an ancient camp, an earthwork enclosure known variously as Erbury, Clare Camp or the Anglo-Roman fort (OS TL768458), at the north end of the town, just to the west of Bridewell Street.  The name Erbury is first seen in an inquest and land valuation in 1295, referring to a house, the land around it and a garden.  This seemed to be part of the largest and most profitable pasture land in the area, lying outside the town and forming a part of Clare Manor.  Erbury means 'earthern fort' from Old English.  Bury is a common placename across Britain and refers to a fortified place: it turns up in various guises across Western Europe: borough, burgh, bourg, burg.

Bălan: Bălan (German: "Kupferbergwerk" ; Hungarian: "Balánbánya" , ] ) is a town in Harghita County, Romania.  It has historically been one of Transylvania and Romania's most important centers for copper mining, but its mines are no longer operational.  Its Romanian name means "blond", the German name means "copper mine" while the Hungarian name means "Balán mine."

Neuf-Brisach: Neuf-Brisach (German: "Neubreisach" ) is a fortified town and commune of the department of Haut-Rhin in the French region of Alsace.  The fortified town was intended to guard the border between France and the Holy Roman Empire and, subsequently the German states.  It was built after the Treaty of Ryswick, in 1697, that resulted in France losing the town of Breisach, on the opposite bank of the Rhine.  The town's name means "New Breisach".
