Geghard is a medieval monastery in the Kotayk province of Armenia, being partially carved out of the adjacent mountain, surrounded by cliffs. It is listed as a UNESCO World Heritage Site with enhanced protection status. While the main chapel was built in 1215, the monastery complex was founded in the 4th century by Gregory the Illuminator at the site of a sacred spring inside a cave. The monastery had thus been originally named Ayrivank, meaning "the Monastery of the Cave". The name commonly used for the monastery today, Geghard, or more fully Geghardavank, meaning "the Monastery of the Spear", originates from the spear which had wounded Jesus at the Crucifixion, allegedly brought to Armenia by Apostle Jude, called here Thaddeus, and stored amongst many other relics. Now it is displayed in the Echmiadzin treasury.

The Khor Virap ( meaning "deep dungeon" is an Armenian monastery located in the Ararat plain in Armenia, near the closed border with Turkey. The monastery was host to a theological seminary and was the residence of Armenian Catholicos. Khor Virap's notability as a monastery and pilgrimage site is attributed to the fact that Gregory the Illuminator was initially imprisoned here for about 14 years by King Tiridates III of Armenia. Saint Gregory subsequently became the king's religious mentor, and they led the proselytizing activity in the country. In the year 301, Armenia was the first country in the world to be declared a Christian nation. A chapel was initially built in 642 at the site of Khor Virap by Nerses III the Builder as a mark of veneration to Saint Gregory.
