The O'Neill Building

"Law & Order: SVU" star Mariska Hargitay sold her incredible Chelsea penthouse back in 2008 for $8.15 million. The duplex spread at the landmarked O'Neill Building (the former Ladies' Mile department store called Hugh O'Neill's Dry Goods Store) spans nearly 5,000 square feet with an additional 2,500 square feet of outdoor space spread across three terraces, one of which sits right next to one of the building's gilded cupolas; inside, there's a bonus room within the cupola. The residence is currently owned by Ewa Laboz. She bought it with her late husband Maurice, who passed away in early 2015, but was a noted millionaire landlord. He made headlines for leaving $20 million to his two daughters, but only if they complied with a list of requirements like getting married, earning a certain salary, and becoming a stay-at-home mom. Despite the hefty fortune he left behind, the family is clearly looking to add to it, as they've listed the apartment for $14 million.
