In 1987, R.M. Harrison of Oxford University conducted a preliminary survey of the site, with excavations being started in 1988. From its inception the Amorium Excavations Project has been principally concerned with investigating post-classical, Byzantine Amorium. During 1989 and 1990, an intensive surface survey was conducted of the man-made mound in the upper city. In 2001, Ali Kaya made a geophysical survey of the church found in the upper city, although a full excavation has yet to be undertaken. The Project is sponsored by the British Institute of Archaeology at Ankara and funded by grants from various institutions in the United States including the Adelaide and Milton De Groot Fund at The Metropolitan Museum of Art and the Friends of Amorium.
