On 30 October 1834, Rev J C Lehner, Rev C L Grainer and Rev Samuel Hebich established the first station of the Basel Mission in a rented house obtained from a Parsi family in Mission Street which was then known as Neereshwalya. The Collector of Mangalore at that time, H M Blair, bought a plot at what was then known as ‘Belmount’ and handed it over to the Basel Mission free of cost. On 11 December 1862, the new church building was consecrated and named the Shanthi Church. By virtue of its strategic location in the Southern Diocese, the Shanthi Church was elevated to the status of Cathedral in the year 1970. C.S.I Sawday Memorial Church, Mandya
