 Tina Turner's widow Erwin Bach is reportedly planning to transform the $76 million Swiss estate where she passed into a museum dedicated to her life and work. Tina, who passed away at the age of 83 on May 24th after battling illnesses for years, lived with her husband Erwin at the sprawling retreat overlooking the shores of Lake Zurich for years. Reportedly, the property is located directly on the water and covers an impressive 59,427 square feet. In addition to the four-story main building, there's a two-story boat house and a sprawling garden. No wonder!
