Guruvayoor Temple is one of the largest and most famed temple in Kerala at national level, attracting more than 5 millions devotees annually. The presiding deity is Lord Vishnu, in form of Sree Krishna 8th incarnation of Lord Vishnu. Hindu mythology says the Lord Krishna used to worship an idol of Lord Vishnu at his palace in legendary Dwarka island. However Krishna knew that, soon after his death, his palace island would wash into seas. He instructed the Deva Guru Heavenly Saint Brihaspati and Vayu Deva Wind God to take his favourite idol, once Dwarka gets submerged and place it in some other place, where devotees can worship. As instructed by Lord, Guru and Vayu took away the idol, when Dwarka was sinking and was hunting a place to the idol. Soon they would a sacred place where they wished to place the idol. However a Shiva temple existed in that area, making it difficult to place the idol nearby. Soon on Guru's invocation, Lord Shiva appeared and agreed to move his temple from the sacred place, to install the divine idol. As Guru and Vayu placed the idol and errected a temple in its honour, the place came to known as Guruvayur.
A large Shiva temple exists at Mammiyur, within a kilometer from the main temple, where the original Shiva temple relocated.
Guruvayur was a royal temple under Kozhikode's Zamorin times. After annexation of Malabar into British presidency, the temple became part a private trust, headed by titular Zamorin ruler and Chief Priest of temple, who were known for their rigid orthodoxies. This resulted in rigid and cruel discrimination based on caste and creed. In 1930s, calls for equality and social reformation started across Kerala and large number of congressmen assembled at Temple gate protesting against the regime of caste discrimination for temple entry, which resulted in closure of temple in 1931. The temple soon was stormed by a group of revolutionaries ending the centuries old pratice of social discrimination. Soon the Madras Presidency nationalized the temple and agreed to allow people of all castes and creed within Hindu fold, to enter the temple, which started the social renaissance in Kerala's caste ridden society of 1930s. Today, the temple is under control of Government of Kerala, managed under Guruvayur Devasom a semi-constitutional temple trustee body. Non-Hindus are strictly debarred and several rigid dress code is in place.
