Monastery of Saint Thaddeus

Lore & Background

According to the tradition of the Armenian Apostolic Church, Saint Thaddeus (also known as Saint Jude) evangelized the regions of Armenia and Persia. The 5th-century Armenian historian Moses of Khorenatsi wrote that Thaddeus suffered martyrdom in Armenia under King Sanatruk. Legend holds that a church dedicated to him was first built on the present site—said to be his burial place—in AD 66, with another source placing the foundation in AD 239 under St. Gregory the Illuminator. Another tradition states that Thaddeus built a monastery at the site for his followers, who buried him there upon his death. The exact date of construction is unknown.

The monastery was damaged in 1231 during the Mongol invasions and again in 1242. Little remains of the original structure, as it was extensively rebuilt after an earthquake in 1319 that killed 75 monks. Parts surrounding the altar apse date from the 7th century. Much of the present structure dates from 1811, when Qajar crown prince Abbas Mirza aided renovations. Father Superior Simeon added a large narthex-like west extension that duplicates the design of Etchmiadzin Cathedral. The 19th-century additions are of ashlar masonry; the earliest sections are black and white stone.

According to Armenian Church tradition, the Apostles Thaddeus and Bartholomew traveled through Armenia in AD 45 to preach. Moses of Khorene told a story, considered a legend by most modern historiographers, that Thaddeus converted King Abgar V of Edessa. After Abgar's death, his son Ananun crowned himself in Edessa while his nephew Sanatruk ruled in Armenia. About AD 66, Ananun ordered the killing of Saint Thaddeus in Edessa. The king's daughter Sandokht, who had converted to Christianity, was martyred with Thaddeus; her tomb is said to be located near the monastery.
