The Norton Simon Museum is known as one of the most exciting private art collections ever. Over the course of 30 years, Nuston Simon (1907-1993) has amassed an astonishing collection of European art from the Renaissance to the 20th century and an impressive collection of 2,000-year-old Southeast Asian art. All are on display here, and modern and contemporary art from Europe and the United States is also part of the gallery. Which makes his collection wide and multi-themes.
