Vilangan Hills (Malayalam: വിലങന് കുന്നു) is a hillock located in Adat Panchayat, near Thrissur city of Kerala state in India. The hill gives a panoramic view of Thrissur city and Thrissur Kole Wetlands from the top. The hill was referred as an Oxygen Jar of Thrissur city. The name 'Vilangan Kunnu' is a misnomer because 'Vilangan' itself means hill. There is no need of adding 'Kunnu' after 'Vilangan'. It is an ancient Malayalam word derived from proto-Dravidian language. Till the 1970s the word 'Kunnu' was not used by revenue authorities and locals. It is a recent addition. In Tamil too 'Vilangan' means hill. The Vilangan is a laterite hill which has a radius of 8 kilometres. The top of the hill is around 5 acres and the height is 80 metres from the sea level. The hill earlier was a military base and an observation camp during World War The Vilangan is a laterite hill which has a radius of 8 kilometres.
