Castle Hill is an underground rapid transit station being built by the Northwest Rapid Transit (NRT) consortium at Old Castle Hill Road, Castle Hill, in Sydney, Australia.
 The station, located opposite the Castle Towers shopping centre, is being built as part of Transport for New South Wales's Sydney Metro Northwest project, to serve future train services to Rouse Hill and Chatswood.
 The station is planned to eventually serve trains to the Sydney central business district, Bankstown and Hurstville as part of the government's 20-year "Sydney's Rail Future" strategy.
A Landesburg or landesherrliche Burg ("sovereign castle", "state castle" or "stately castle") was a castle that a territorial lord, such as a prince-bishop, duke or prince built for the defence or expansion of his sovereign estates.
 They were thus the central and most important castles of the great princely territories.
 The "Landesburgen" were usually the property of the territorial lord, but they sometimes referred to castles that he did not own, but were available to him as a safe house ("Offenhaus").
 The large castles of the 8th to 10th centuries, east of the Rhine and outside the towns were often described as "Landesburgen" because they performed important functions in the control of the state.

Bastian Pagez was a French servant and musician at the court of Mary, Queen of Scots.
 He devised part of the entertainment at the baptism of Prince James at Stirling Castle in 1566.

Lenzburg Castle (German: "Schloss Lenzburg" ) is a castle located above the old part of the town of Lenzburg in the Canton of Aargau, Switzerland.
 It ranks among the oldest and most important of Switzerland.
 The castle stands on the almost circular castle hill (altitude: 504 m), which rises approximately 100 m over the surrounding plain but is only about 250 m in diameter.
 The oldest parts of the castle date to the 11th century, when the Counts of Lenzburg built it as their seat.
 The castle, its historical museum and the castle hill with its Neolithic burial grounds are listed as heritage sites of national significance.
Castles have played an important military, economic and social role in Great Britain and Ireland since their introduction following the Norman invasion of England in 1066.
 Although a small number of castles had been built in England in the 1050s, the Normans began to build motte and bailey and ringworks castles in large numbers to control their newly occupied territories in England and the Welsh Marches.
 During the 12th century the Normans began to build more castles in stone – with characteristic square keeps – that played both military and political roles.
 Royal castles were used to control key towns and the economically important forests, while baronial castles were used by the Norman lords to control their widespread estates.
 David I invited Anglo-Norman lords into Scotland in the early 12th century to help him colonise and control areas of his kingdom such as Galloway; the new lords brought castle technologies with them and wooden castles began to be established over the south of the kingdom.
 Following the Norman invasion of Ireland in the 1170s, under Henry II, castles were established there too.
Henry House Hill is a location near Bull Run in Virginia.
 Named for the house of the Henry family that sits atop it, the hill begins near the road of Centreville, Virginia, after Gainesville, Virginia, to the today's U.S. Route 29, the Warrenton Turnpike.
 It is a slow, constant rise toward the south over a length of approximately 730 meters.
 This hill was an important site of the battles of First and Second Bull Run (also known as First and Second Manassas) in the American Civil War.
 The battle raged on the north side of the hill in predominantly open grass country; the south side was relatively closely covered with trees.
 The hill received its name from Dr. Isaac Henry, who lived with his family in a house on the plateau of the hill.
 On July 21, 1861, the house was inhabited by his widow, Judith Carter Henry, and their two sons.
 The 85-year-old woman was bed-ridden and unable to leave the house.
 Mrs. Henry was mortally wounded when a projectile of the Union artillery crashed through the bedroom wall and tore off one of her feet and inflicted multiple injuries, from which she died later that day.
Stirling Castle, located in Stirling, is one of the largest and most important castles in Scotland, both historically and architecturally.
 The castle sits atop Castle Hill, an intrusive crag, which forms part of the Stirling Sill geological formation.
 It is surrounded on three sides by steep cliffs, giving it a strong defensive position.
 Its strategic location, guarding what was, until the 1890s, the farthest downstream crossing of the River Forth, has made it an important fortification from the earliest times.
