Inside the narthex one gets a good impression of how rich the church looked in its heyday. The roof is particularly well decorated. The Wikipedia has "The date of its construction is not known, but the earliest dated inscription on its walls is from 1031. It was founded by the Pahlavuni family and was used by the archbishops of Ani (many of whom belonged to that dynasty). It has a plan of a type called an inscribed quatrefoil with corner chambers. Only fragments remain of the church, but a narthex with spectacular stonework, built against the south side of the church, is still partially intact. It dates from the early 13th century." Elsewhere can be read that the south narthex is sometimes erroneously called a "Seljuk caravanserai". It also is my experience that Arak'elots is spelled apart or connected.
