Archangelskoye State Museum Estate
This 18th century real estate, a little outside Moscow, was founded by the Yusopov family. The last owner, Felix Yusopov, tried to save the tsars by murdering the orthodox monk Rasputin in 1916. He fled Russia in 1919, taking with him two cut out of frame Rembrandts, which are now in the possession of the National Gallery in Washington.
The most significant objects in the collection of Yusopov disappeared to other museums, such as the Hermitage Museum in St. Petersburg and the Pushkin Museum in Moscow. The rest of the collection, amongst which are several Dutch and Flemish paintings, remained in the estate.
