Khulna Zilla School is the oldest high school in the Khulna district of Bangladesh, located at Lower Jessore Road, Khulna. Most believe that it was established in 1873. On the recommendation of the Hunter Commission Report of 1883, the British Government of India took over the control and management of the school in April 1885. A new red brick building was constructed at that time and the school was renamed as ‘Khulna Zila School’. As it was RED in colour; local people also called it ‘Lal Dalan’ or ‘The Red Building’.
