The mansion from one of Taylor Swift's most well-known music videos is up for sale. Woolworth Estate was the backdrop for the <i>Blank Space</i> video, in which Swift played the role of a rich, jealous woman whose relationship gradually deteriorates. The video oozes glamour, and is filled with extravagant ballgowns, vintage cars, horses and stately manors. What most fans don’t know is that one mansion simply wasn’t enough to capture the video's luxury settings. While the sweeping grounds and exteriors were filmed at the Oheka Castle, the interiors were filmed at Woolworth Estate, also known as Winfield Hall, on Long Island, New York. And now, one lucky fan can have the chance to live in the latter, which is up for auction on Monday, July 12. The Woolworth Estate, set amid 7 hectares of land, is a sprawling 12-bedroom home. The property also includes sweeping lawns with classic sculptures and a clock tower building with a garage large enough to house eleven cars. Woolworth Estate is one of the last privately owned estate homes of its era, designed by renowned architect Charles Gilbert. It's also part of the National Register of Historic Places in the US since 1979, ensuring that it cannot be demolished. It's expected to sell for $7million at the auction by Max Spann, which concludes on Wednesday, July 14. Swift fans will likely recognise several rooms from the video. The Music Room doubles up as a dining room where Swift and model Sean O'Pry are seen sitting on an elegant dining table. The duo are also seen dancing within the mansion, while Swift is later seen crying in front of a marble fireplace on the floor hallway. <br/> According to <i>House Beautiful </i>magazine, Swift has left a little mark within the mansion as well; on one of the first steps of the marble staircase, there’s a piece of tape indicating where the Grammy Award-winning singer should stand during the filming of the video. The furniture, which also includes a Versace dining set, will be sold separately.
