An architectural delight, this majestic building houses a picture gallery of mural paintings from all over Kerala. Apart from these, there is also a collection of rare veerakallu, temple models, olagrandhangal (manuscripts on dry palm leaves), megaliths and so on. Veerakallu or 'herostones' are stone engravings and sculptures of figures and weapons belonging to the heroes of yesteryears. The temple models in Plaster of Paris are excellent representations of the ancient temples in the State.
