The theme of the AKLF this year was Park Street, so when approached to conduct heritage walks for the citizens and the delegates, it was only pertinent that CHC does one walk in the Park Street area, an area which is replete with history and heritage but is not known to many. The Dalhousie Square Trails was conducted on the 20th January 2019 which was a walk to know the hows and whys of Calcutta helping one to retrace the steps that gave birth to the great city.
