Among the heritage structures,  the building that houses the Kolkata Police Headquarters in Lal bazaar  stands out as a distinct landmark in that locality, close to the  Tank Square or Dalhousie Square ; in the early days it was an area of ill-repute known for thugs. The street  was known as  Flag Street, for the simple reason it was the hub of visiting sailors. The name had its origin in the presence of a market place  built  by one Edward Tiretta,  Yet another reason  for the name La bazaar is one can see the reflection of the near-by  brick-red  Writer's building in the Tank, hence it was called “Laldighi" and later it became Lal bazaar (Lal in Hindi means red). Further, during the festival days this locality used to become red  littered with red Aabir.
