English: Dinantika built in 1939, is an octagonal two-storeyed structure originally used as a tea-house with the staircase on the outside; staff members of Visva-Bharati would meet in the evening for a cup of tea and relaxation. The Cha Chakra, as it was called, was instituted in the name of Dinendranath Tagore by his wife, Kamaladevi. The walls of this house have colourful frescoes by Nandalal Bose.
