Art worth of 91 million dollars was stolen from a museum in Zurich on Sunday, according to police.

According to Bernd Quellenberg, a spokesman for the Kunsthaus, an important art museum in Zurich, the paintings by Paul Cezanne, Edgar Degas, Claude Monet and Vincent van Gogh were stolen by armed robbers from an art foundation's gallery in Zurich, Switzerland.

According to Police in Zurich, the paintings were valued at 100 million Swiss frances (91 million dollars).

The art gallery from which the works of art were stolen is maintained by the Emil-Georg Byhrle private art foundation and the director of the Kunsthaus works for the council of the foundation.

The foundation was created by a Zurich industrialist and it contains mainly Impresionist works. The website of the museum says: "French Impressionism and Post-Impressionism constitute the core of the collection," AFP reports.

Police called the theft a ''spectacular art robbery.''

The heist comes just days after two other paintings were stolen from a cultural centre in eastern Switzerland. The works were two paintings in oil by Pablo Picasso and were worth 4.5 million dollars.

The 1962 "Tete de Cheval" ("Horse's Head") and the 1944 "Verre et Pichet" ("Glass and Pitcher"), were stolen on February 6 and were on loan from the Sprengel Museum in Hannover, Germany.

On Monday a press conference is expected to be held by police.
