<P> In 1914, von Steingel sold the building to P.G. Shelaputin to be used as a restaurant . For a short time after the 1917 Russian Revolution, the building was used only as a tourist attraction . In 1927, the Swallow's Nest survived a serious earthquake rated at 6 to 7 on the Richter scale . The building was not damaged apart from some small decorative items that were thrown into the sea along with a small portion of the cliff . However, the cliff itself developed a huge crack . In the 1930s, the building was used by a reading club from the nearby "Zhemchuzhina" (Pearl) resort, however it was closed shortly thereafter as a safety precaution due to the damage it had suffered in the quake, remaining closed for the next 40 years . </P> <P> Renovation and restoration of the building was started only in 1968 . The project involved the restoration of a small portion of the castle and the addition of a monolithic console concrete plate to strengthen the cliff . Since 1975, a restaurant has operated within the building . In 2011, the Swallow's Nest was closed for three months due to major restoration work estimated to cost 1,200,000 hryvnias ($150,000 USD). </P> <P> Owing to its important status as the symbol of the Crimea's southern coast, the Swallow's Nest was featured in several Soviet films . It was used as the setting of Desyat Negrityat, the 1987 Soviet screen version of Agatha Christie's And Then There Were None . The building was also featured in the 1983 Soviet - Polish children's film Mister Blot's Academy as well as in Mio in the Land of Faraway, a 1987 joint production by Swedish, Norwegian, and Soviet film companies . </P>
