The Danish Modern movement helped shape the world of modern living, and some iconic 20th-century buildings were designed by Danish architects, such as the Sydney Opera House (Jørn Utzon) and La Grande Arche in Paris (Johan Otto von Spreckelsen). Since the 1990s, Danish architecture has increasingly focused on Neo-Modernism and issues surrounding sustainability. Denmark has developed a tradition for modern design in arts and crafts, and annual exhibitions at major design fairs are curated by the Danish Agency for Culture. There are leading galleries and museums featuring ceramics and glass, and Bornholm is known as an 'island of artisans'. However, the Danish Golden Age of the 19th century is also celebrated for contributions to painting, sculpture, music, philosophy, architecture, and in literature Hans Christian Andersen was a leading proponent of the modern fairy tale.
