The cathedral of the Archdiocese is the Cathedral of Mary Help of Christians, in Shillong. It was built over 50 years ago. This place of worship stands on the very site of the first Church built by the German fathers (Salvatorians from Germany).

The earlier 1913 building – the Church of the Divine Saviour – was a wooden structure. It was destroyed in the Good Friday fire of 10 April 1936. Built by the first Catholic missionaries to set foot on these hills, the Salvatorians from Germany, it was the first Catholic Cathedral in what was then the Mission of Assam.
