This mission campus is situated in the centre of Kalimpong town, on Relli Road. This plot of land was purchased by Fr Gex Collet to build the present church of Relli Road as it is commonly known. The Church was separated from St. Teresa’s Church, Kalimpong in 1974. On 1st January 1978, the Church was blessed by His Lordship Bishop Eric Benjamin and called it Mary, Mother of God Church. The church is built in gompa style without any pillars inside.
Fr Gex was the first Parish Priest of this church. The first baptism in the Mary, Mother of God Church was of Teresa Margaret Rai by Fr Gex Collet on 03.01.1978.
Fr. Lawrence Monteiro is the present Parish Priest.
