Vivekanandar Illam, earlier known as Ice House or Castle Kernan, is a historical building in Chennai, India.

In 1880, the business collapsed and the building was sold to Biligiri Iyengar, an advocate in the Madras High Court.

Iyengar re-modeled the house and named it Castle Kernan after his friend and judge in Madras High Court.

[citation needed] In 1914, the building was acquired by the Government of Madras and functioned as a hostel and training school for children run by R. S. Subbalakshmi.

In 1997, Government of Tamil Nadu leased the building to Ramakrishna Math, and it currently houses an exhibition on the life of Swami Vivekananda.
