Acharya Bhaban preserves the north Kolkata house associated with scientist Jagadish Chandra Bose. The small museum displays instruments he designed and used, along with personal belongings and memorabilia that place his work in the everyday setting of his home.
It is a worthwhile stop if you are interested in Bengali science, education, and the reformist world that shaped late colonial Kolkata. Combine it with other north-city sights rather than treating it as a stand-alone half-day visit.
