Thimmamma Marrimanu is the name of a Banyan tree in Anantapur district, located about 35 km from town Kadiri in the state of Andhra Pradesh, India.[2] It is present in the Indian Botanical Gardens and is more than 200 years old.[3] It is reported to be the world's biggest tree with a canopy of 19,107 square metres.[4] Its branches spreads over 8 acres, and hence was recorded as the biggest tree in the Guinness Book of World Records in 1989.[5][6] A small temple dedicated to Thimmamma lies under the tree. An account of this lady in Telugu kept at the shrine reveals that she was the daughter of a Setti Balija couple Sennakka Venkatappa and Mangamma, born in AD 1394. She was married to a Bala Veerayya who died in 1434, and Thimmamma committed Sati. The banyan tree is believed to have sprouted at the place where she ascended the funeral pyre.[7] The people of this area strongly believe that if a childless couple worship 'Thimmamma' they will have a child the very next year. A big jatara is conducted here on the day of Shivaratri festival when thousands of people flock here to worship 'Thimmamma' on this occasion.[8]
