Pushkin Museum of Fine Arts

The Pushkin Museum of Fine Arts is the largest museum of European art in Moscow, located in Volkhonka street, just opposite the Cathedral of Christ the Saviour.

The museum's name is misleading, as it has nothing to do with the famous Russian poet. It was founded by professor Ivan Tsvetaev (father of the poet Marina Tsvetaeva). Tsvetaev persuaded the millionaire and philanthropist Yuriy Nechaev-Maltsov and the fashionable architect Roman Klein of the urgent need to give Moscow a fine arts museum.
