In addition to possible middle Byzantine remains seen at Gargara by John Cook, other documents such as the Epistulae Dogmaticae of Patriarch Germanus I of Constantinople (715-730) and the Notitiae Episcopatuum also attest Gargara's continued existence throughout this period. Finally, four documents from the Monastery of Great Lavra on Mount Athos dating to 1284 and 1304 attest a Constantine of Gargara and his family.
This information is reinforced by additional potential late Byzantine remnants at Gargara observed by John Cook, as well as other documents such as the Dogmatic Epistles of Patriarch Germanus I of Constantinople (715-730) and the Bishopric Records, which confirm that Gargara remained in existence throughout this period. Additionally, four documents from the Monastery of Great Lavra on Mount Athos dating to 1284 and 1304 also mention a Constantine of Gargara and his family.
