Ramakrishna Mission Swami Vivekananda's Ancestral House & Cultural Centre
"Ramakrishna Mission restored the Ancestral House of Swami Vivekananda without changing any of its original architectural features. This feat of skilled workmanship was accomplished with the technical assistance of the Archaeological Survey of India and the Development Consultants Pvt. Ltd. It should be mentioned here that for this restoration work the same or similar materials as used in the original 18th century construction have been used. The restored ancestral house was thenceforth called the Heritage Building."
