[3] Krishnapuram Palace is one of the finest and rarest examples of a typical Keralite style of architecture - complete with gabled roofs, narrow corridors and dormer windows.

Residence of the rulers of Kayamkulam kingdom (Oodanadu Raja Vamsham), the age of the palace is unknown.

Renovated some time in the 18th century, the palace is today a protected monument under the Archaeology department.

Today the palace is an archaeological museum, and the most fascinating exhibit here is the 49 sq.m Gajendra Moksham, the largest single band of mural painting so far discovered in Kerala.

The theme of the mural is mythological and depicts an elephant saluting Lord Vishnu in devotion while the other gods, goddesses and saints look on.
