The Mother See of Holy Etchmiadzin found in the city of Vagharshapat, Armenia is a blend of the past, present and future of the worldwide Armenian Church and contains the main church, monuments, museums and the pontifical residence. It was built in the days of Gregory the Illuminator and King Tiridates III in the place where, according to Armenian Church traditions, the Descent of Christ happened in Vagharshapat, Armenia, also known as Etchmiadzin. The wooden church was rebuilt in stone in the V and VII centuries. The bell tower was built in 1653 and the vestry in 1869.
The complex includes the Etchmiadzin Cathedral (Armenian: Մայր Տաճար Սուրբ Էջմիածին), the vestry, residences, museums, Gevorkian Theological Seminary and many other amenities.
