1.This short walk along a couple of blocks of old Moscow begins at the Barrikadnaya station. Walk up the hill and cross over the Ring Road, bearing to the right of the Tchaikovsky Center. This is the end of Povarskaya Ulitsa, Cook's Street, where the tsar's household kitchen staff once lived. This end of the street, however, had larger lots for the aristocracy's manor house and gardens. Almost every building on this street has a history, beginning with the yellow and white mansion on the left. Behind a tall wrought-iron fence, the arms of low buildings reach out from the main building to surround a snowy courtyard. First built in the late 18th century, the house was updated with a more classical appearance a century later. Once owned by the very princely Dolgorukovs, it is believed to be the prototype of the Rostov mansion in Leo Tolstoy's "war and peace", although other scholars doubt this. What is not in doubt: the literary pedigree. Over the years it has been a literary salon, a palace of culture, a writer's union, and literature institute, where every star in Russia's literary firmament either spoke, or visited or taught. In the center of the courtyard is a statue of Tolstoy.
