The exhibition also covers other festivals like Pilgrimage to Chinsurah, when members of the community go on an annual pilgrimage to St John, the Baptist, Armenian Church in the erstwhile Dutch settlement of Chinsurah.
Celebrated every year on the Sunday after the Armenian Christmas, the pilgrims carry the golden hand of St John who is said to have baptised Jesus Christ in the waters of the Jordan river.
