Question: In what country is the castle that was the Seat of the Culdares line?
Context: Sigmaringen Castle (German: "Schloss Sigmaringen") was the princely castle and seat of government for the Princes of Hohenzollern-Sigmaringen.  Situated in the Swabian "Alb" region of Baden-Württemberg, Germany, this castle dominates the skyline of the town of Sigmaringen.  The castle was rebuilt following a fire in 1893, and only the towers of the earlier medieval fortress remain.  Schloss Sigmaringen was a family estate of the Swabian Hohenzollern family, a cadet branch of the Hohenzollern family, from which the German Emperors and kings of Prussia came.  During the closing months of World War II, Schloss Sigmaringen was briefly the seat of the Vichy French Government after France was liberated by the Allies.  The castle and museums may be visited throughout the year, but only on guided tours. 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. The title Menzies of Culdares came to prominence following the extinction of the main Menzies of Weem line in 1911.  The Clan was without a Chief until Col. Ronald Steuart Menzies of Culdares and Arndilly, the lineal heir of Colonel James Menzies of Culdares, a prominent Covenanting officer and cousin of the first Baronet, petitioned Lyon Court in 1957 and obtained arms in the title of "The Menzies of Menzies".  His son, David Steuart Menzies of Menzies is the present Chief.  The title Menzies of Culdares was matriculated to his second son, Simon Menzies of Culdares, in 2006.  Meggernie Castle in Glen Lyon, Perthshire was the Seat of the Culdares line Milntown Castle was an early 16th-century castle which was situated near Milton, in Easter Ross, in the Scottish Highlands.  It was built by the Munro of Milntown family, a cadet branch of the Clan Munro.  In 1656, the castle and estate was sold to George Mackenzie, 1st Earl of Cromartie also known as George MacKenzie of Tarbet.  He renamed the estate New Tarbat after Tarbat Castle (now more commonly known as Ballone Castle), the family's original seat near Portmahomack.  Mackenzie had the Milntown Castle pulled down and only part of the basement survives.  He then replaced the castle with a new mansion built nearby.  When the new mansion was built, the old Milntown Castle was remodelled as part of the garden.  That mansion was itself demolished and in 1787 was replaced with a Georgian house (now known as Tarbat House) by his descendant John Mackenzie, Lord MacLeod. Osu Castle, also known as Fort Christiansborg or simply the Castle, is a castle located in Osu, Accra, Ghana on the coast of the Atlantic Ocean's Gulf of Guinea.  The first substantial fort was built by Denmark-Norway in the 1660s, though the castle has changed hands between Denmark-Norway, Portugal, the Akwamu, Britain, and finally post-Independence Ghana, and was rebuilt numerous times.  For most of the castle's history, it has been the seat of government in Ghana with some interruptions, the latest when the John Kufuor administration moved the seat of government to Golden Jubilee House after 6 January 2009, which was quickly reversed by the incoming John Atta Mills administration.  It also serves as the place where the late president of Ghana John Atta Mills is buried; in a bird sanctuary, overlooking the Atlantic Ocean. Meggernie Castle is a castle in the heart of Perth and Kinross, in central Scotland.  It is located halfway up Glenlyon, where the river Lyon flows through on its way to join Loch Tay.  From the 1920s until the 1950s, the castle was owned by Sir Ernest Wills, 3rd Baronet. Anthony Salvin (1799–1881) was an English architect, born in Sunderland Bridge, County Durham.

Hall in the parish of Lanteglos-by-Fowey in Cornwall, England, is an historic estate, most prominent as the seat of a branch of the Mohun family, feudal barons of Dunster, of Dunster Castle in Somerset, of whom the first member, the warrior William de Moyon (died post 1090), had come over with William the Conqueror during the Norman Conquest of 1066.  The family of Mohun of Hall was also seated at Bodinnick ("alias" Bodinnoc, etc.) also in the parish of Lanteglos-by-Fowey and later at Boconnoc, both in Cornwall, and was one of the four co-heirs of Edward Courtenay, 1st Earl of Devon (1527–1556), feudal baron of Okehampton, etc., of Tiverton Castle, Okehampton Castle, etc., the last of the mediaeval Courtenay Earls of Devon.  In recognition of this in 1628 the senior representative of the Mohun family of Hall was created Baron Mohun of Okehampton, namely John Mohun, 1st Baron Mohun of Okehampton (1595-1641) eldest son and heir of Sir Reginald Mohun, 1st Baronet (1564–1639) of Boconnoc.  The family of Mohun of Hall died out in the male line in 1712, following the death by duel of Charles Mohun, 4th Baron Mohun of Okehampton (1677-1712), who died without progeny.  However, the family had long out-lived the senior Dunster line which died out in the male line in 1375, following the death of John de Mohun, 2nd Baron Mohun, KG, (c.1320-1375).  Two monumental brasses survive in Lanteglos church to members of the Mohun family of Hall, namely Thomas Mohun (died c.1440) and John Mohun (d.1508). Ambras Castle (German: "Schloss Ambras Innsbruck" ) is a Renaissance castle and palace located in the hills above Innsbruck, Austria.  Ambras Castle is 587 m above sea level.  Considered one of the most popular tourist attractions of the Tyrol, Ambras Castle was built in the 16th century on the spot of an earlier 10th-century castle, which became the seat of power for the Counts of Andechs.  The cultural and historical importance of the castle is closely connected with Archduke Ferdinand II (1529–1595) and served as his residence from 1563 to 1595.  Ferdinand was one of history’s most prominent collectors of art.  The princely sovereign of Tyrol, son of Emperor Ferdinand I, ordered that the mediaeval fortress at Ambras be turned into a Renaissance castle as a gift for his wife Philippine Welser.  The cultured humanist from the House of Habsburg accommodated his world-famous collections in a museum built specifically for that purpose, making Castle Ambras Innsbruck the oldest museum in the world. Świny Castle (Polish: "Zamek Świny"; formerly "Schweinhausburg" in German) - formerly a gord, as a stronghold existed in its location already in the fifth century - securing the Lubawecki mountain pass, the site was recorded in Cosmas' documents from 1108, where the gord is recorded as "Suini in Poloniae".  Possibly, soon after, the gord had been expanded into a military stronghold, at which time it was the seat of the castellans.  The castle was mentioned in Pope Adrian IV's Papal bull.  After the Bolków Castle was constructed, the castle began to lose its significance, this continued up to the nineteenth century, when the castle suffered severe damage due to hurricanes (1762, 1840, 1848, and 1868).  The castle suffered further devastation - it was not until 1931 when the authorities had engaged in securing the castle's ruins.  Currently the castle is privately owned.
