Khitrov marketplace (Russian: Хитров рынок), also known as Khitrovka (Russian: Хитровка), was a square in the centre of Moscow from 1820 to 1930. This square was located in place of today’s house №11a in Podkolokolny lane. In the second half of the 19th century Khitrovka became a bawdy place of Moscow, a den for thousands of unemployed and criminals. It is described by V.A. Gilyarovsky, C.S. Stanislavsky and other authors.
