Prepare to discover the unknown mysteries, spectacular shows, art performances and exclusive parties in the capital's most respectable art galleries and museums... at night!

Over a hundred art venues are holding what has become an annual event in Russia since 2007. “Night in the Museum” will be held this weekend in Moscow, and here are some hints on where to go on this unusual day. The fourth museum night will start at 19:00 on Saturday.

The geography of the "Night" will cover almost all city districts. Among others, the Tretyakov Gallery, Moscow's Archeological, the Historical Museum, Gulag History Museum, the State Shchusev Museum of Architecture, and the Winzavod and Garage contemporary art centers are participating. The list is long.

"It is the fourth time the doors of the Moscow museums and galleries will be open on a May night… The best art can be seen in an unusual time and in unusual circumstances," said the mayoralty.

This year the Tretyakov Gallery in the Central House of Artists is getting ready to entertain visitors with the opening the "Sanatorium of Arts: Branch of ARThopedics and Aesthetic Traumatology." The Fleet History Museum will meet visitors with a special Russian naval dish, fleet macaroni, and take them on a tour on a submarine. Right next to the Central House of Artists, the Museon Park will be the site for a light show close to midnight, and from 18:00 to 21:00 for master classes on painting, sculpture and smith craft.
