Ulitsa Petrovka is known for its theatres, including the ultra-famousBolshoi, and for being the height of luxury! It once led to theUpper Monastery of St Peter without the walls, to which it owes its name. It was accordingly lined with mansions belonging to the Muscovite nobility, now replaced by chic boutiques. Fashion addicts will want to check out Tsum, a true temple of fashion, and Petrovsky Passage illuminated by a lovely glass roof.
