Kathisma

The Church of the Seat of Mary, Church of the Kathisma or Old Kathisma being the name mostly used in literature, was a 5th-century Byzantine church in the Holy Land, located between Jerusalem and Bethlehem, on what is today known as Hebron Road. It was built on the alleged resting place of Mary on the road to Bethlehem mentioned in the apocryphal Proto-Gospel of James. The church was built when Marian devotion first rose to great importance, following the First Council of Ephesus of 431. It is one of the earliest churches known to have been dedicated to the Theotokos in the entire Byzantine Empire.
