In 1967, HRH the Duke of Württemberg bought Darkwoods, a large tract of land in British Columbia. According to the Globe and Mail, the duke bought the land on the "eve of the Soviet takeover of Czechoslovakia." The Soviet invasion of Czechoslovakia was in August 1968. The manager said that the Duke had bought Darkwoods "as a safe haven for his family." The Duke, who is married to Princess Diane of France, used to visit the estate once a year "until no-smoking regulations put him off long-distance travel."
Darkwoods was bought for $125 million (Canadian) dollars by Nature Conservancy Canada.
