This book is a collection of heritage buildings, many of which are inaccessible to civilians. Most others would be dreaded by civilians. These buildings belong to the proud 166 year old heritage of Kolkata Police, the oldest Commissionerate in the country. Kolkata Police Commissioner Soumen Mitra is credited with efforts to restore and renovate these buildings, some of which were in a state of complete ruin. Today they are being used for police housing or administrative purposes.
