Balloch Castle is an early 19th-century country house situated at the southern tip of Loch Lomond, in West Dunbartonshire, Scotland.
 Balloch was a property of the Lennox family from the 11th century, and the old castle was built in the 13th century.
 In the 19th century the estate was purchased by John Buchanan of Ardoch, who demolished the ruins of the old castle and erected the present building.
 The Tudor Gothic architecture is the work of Robert Lugar.
 In 1915 Balloch was bought by Glasgow City Corporation, and has been leased by West Dunbartonshire Council since 1975.
 The estate was designated as a country park in 1980, and since 2002 has been part of Loch Lomond and The Trossachs National Park.
 Although the house has been periodically used for visitor facilities and council offices, it is now included on the Buildings at Risk Register.
 Balloch Castle is a category A listed building, and the estate is included on the Inventory of Gardens and Designed Landscapes in Scotland.
Country house opera is opera performed at a country house, whether in the house itself, in the grounds, or in an adapted or purpose built theatre on the grounds.
 It is a feature in particular of the English summer.
 Country house opera is usually initiated by private enthusiasts, and relies almost exclusively upon private funding.
 This distinguishes it from the UK's state subsidised opera companies which, like most opera houses around the world, are based in city centres.
 Black tie is often "de rigueur", in contrast with the Royal Opera House in London and other city operas where casual clothing is often acceptable.

 The site was occupied from the Middle Ages, and the house incorporates part of a 17th-century castle.

 It was the seat of the Gordon family of Lochinvar, later raised to the peerage as Viscounts of Kenmure.
 The castle is located in The Glenkens, 1 mi south of the town of New Galloway.

Buchanan Auld House (or Buchanan Old House) is a ruined house in Stirlingshire, Scotland, located 1.5 mi west of the village of Drymen.
 Historic seat of the Clan Buchanan, the house was the property of the Chiefs of Clan Buchanan who controlled the surrounding lands from at least 1231 until 1682.
 Following the death of John Buchanan in the late 17th century, the estate passed to the Grahams who substantially rebuilt the house during the 18th century.
 The property burned down in 1852 and James Graham, 4th Duke of Montrose commissioned the country house of Buchanan Castle as a replacement, which was built in 1852-1858 and stands 0.5 mi to the southeast.
 The ruins of Buchanan Auld House exist today as part of a courtyard attached to the clubhouse of the Buchanan Castle Golf Club, which occupies the surrounding lands.
Hatton Castle stands on the lower part of Hatton Hill, the most easterly of the Sidlaw Hills, to the south of Newtyle in Angus, Scotland.
 The castle overlooks the wooded Den of Newtyle, and its views extend across Strathmore and include Ben Lawers and Schiehallion as well as the Angus and Glenshee hills.
 The 16th-century castle was originally built in a typical Scottish "Z plan" tower house design, as a fortified country house or "château".
 There was an earlier castle called Balcraig Castle which stood less than half a mile from the present building, also on Hatton Hill.
Belton House is a Grade I listed country house in Belton near Grantham, Lincolnshire, England.
 The mansion is surrounded by formal gardens and a series of avenues leading to follies within a larger wooded park.
 Belton has been described as a compilation of all that is finest of Carolean architecture, the only truly vernacular style of architecture that England had produced since the Tudor period.
 The house has also been described as the most complete example of a typical English country house; the claim has even been made that Belton's principal facade was the inspiration for the modern British motorway signs which give directions to stately homes. Only Brympton d'Evercy has been similarly lauded as the perfect English country house.
Edzell Castle is a ruined 16th-century castle, with an early-17th-century walled garden.
 It is located close to Edzell, and is around 5 mi north of Brechin, in Angus, Scotland.
 Edzell Castle was begun around 1520 by David Lindsay, 9th Earl of Crawford, and expanded by his son, Sir David Lindsay, Lord Edzell, who also laid out the garden in 1604.
 The castle saw little military action, and was, in its design, construction and use, more of a country house than a defensive structure.
 It was briefly occupied by English troops during Oliver Cromwell's invasion of Scotland in 1651.
 In 1715 it was sold by the Lindsay family, and eventually came into the ownership of the Earl of Dalhousie.
 It was given into state care in the 1930s, and is now a visitor attraction run by Historic Scotland (open all year; entrance charge).
 The castle consists of the original tower house and building ranges around a courtyard.
 The adjacent Renaissance walled garden, incorporating intricate relief carvings, is unique in Scotland.
 It was replanted in the 1930s, and is considered to have links to esoteric traditions, including Rosicrucianism and Freemasonry.
