Stoehr (2018:127–130) identifies Temple T2 as the so-called third temple and explains that this phase was constructed to encase and closely replicate the earlier second temple, preserving many of its architectural elements while enlarging the overall scale of the structure.

Stoehr notes that “at some point near the end of the fourth century the third temple was severely damaged, likely the result of the large earthquake of 363 CE.” The building was never repaired, and the temenos instead underwent a major functional shift. A small Christian chapel was constructed within the enclosure, incorporating the remains of the large temple altar as the foundation of its north wall. A second church-like structure was begun on the temple podium but apparently left unfinished; its floor had been rebuilt using reused materials and spolia after being “most likely damaged beyond repair by the earthquake of 363 CE.” Ceramic and numismatic evidence from fill associated with this rebuilding indicates a date in the second half of the fourth century.

Later activity reflects both continued collapse and long-term reuse of the monument. An architrave block that had “evidently fallen” was reused to block the original temple doorway, possibly to restrict access to a dangerous structure. Industrial installations and other buildings were later constructed against the temple podium, only to be followed by additional collapse of architectural blocks that fell from higher courses onto already-abandoned structures. Quarrying of temple stone continued for centuries, with sorted piles of blocks indicating sustained spoliation into the thirteenth century CE.
