Built during the period of King Anizham Thirunal Marthanda Varma (1729-1758 AD), Krishnapuram Palace in Alappuzha district houses the largest single band of mural painting so far discovered in Kerala. The three-metre high mural depicts ‘Gajendra Moksham,’ the Puranic story of Lord Vishnu rescuing the elephant Gajendra from the clutches of a crocodile. Covering an area of 1.87 acres, the palace-turned-archaeological museum showcases burial urns, stone sculptures, bronze antiquities, swords, measuring vessels and cannonballs from the late medieval period.
