Originally built for New York investor Henry Sanderson, the 40-room Italian Renaissance-inspired compound in Upper Brookville has seen several owners since its construction in 1915. The 24-acre estate served as the St. Francis Retreat House for the Roman Catholic Church before it was purchased in 2001 by Sylvia Kumar, wife of convicted securities fraudster Sanjay Kumar, former CEO of Computer Associates. The immense 7-bed/7-bath mansion has a walled carriage house, five indoor horse stables, a guest cottage, library and two dining rooms and features intricate architectural elements like a domed rotunda, tooled columns and arches, wrought iron doors and Renaissance-style paintings. After pleading guilty and being handed a 12-year prison term, Sanjay in 2007 was ordered to pay shareholders $798.6 million in restitution. Sylvia previously tried to sell the house for $17 million and if she doesn’t get a bite for $14.5 million, plans to divide the estate into five-acre plots seem imminent. [via luxist]
