Château d'Amboise
Oliver Belmont died on June 10, 1908, at his Brookholt estate in East Meadow, New York, from appendicitis. He was interred in the Woodlawn Cemetery in The Bronx. His mausoleum, designed by Richard Morris Hunt, is an exact replica of the Chapel of St. Hubert at Château d'Amboise in France and features a set of Renaissance-inspired painted glass windows designed by artist Helen Maitland Armstrong. His second wife, Alva Belmont, was buried alongside him after her death in 1933.
