The Wizard of the Emerald City (Russian: Волшебник Изумрудного Города ) is a 1939 children's novel by Russian writer Alexander Melentyevich Volkov.
 The book is a re-narration of L. Frank Baum's "The Wonderful Wizard of Oz".
 Baum's name is sometimes credited in the book (in the appendix by Volkov, which is found in some editions, where Volkov describes the origins of his book).
 The names of most characters are changed, some elements of Baum's novel are removed, and some new elements are added.
 The book was illustrated by Leonid Vladimirski in 1959 and became quite popular in the 1960s, leading to five sequels: "Urfin Jus and his Wooden Soldiers" (1963), "The Seven Underground Kings" (1964), "The Fiery God of the Marrans" (1968), "The Yellow Fog" (1970), and "The Secret of the Abandoned Castle" (1975, published in 1982).
 These sequels were written by Volkov himself and are not based on Baum's plot elements, although we do encounter the powder of life, a character called Charlie Black who is not unlike Cap'n Bill, intelligent foxes, and the use of a Sandboat similar to Johnny Dooit's, albeit with wheels.
Kinlochaline Castle is a 12th-century Scottish fortress on the Ardtornish estate in Morvern in the Highland council area.

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.
