The church was built at the end of the 10th century. Historically, the first source that informs us of the existence of the Monastery are two notes from 1193, in the Gospel of the
Monastery of Mega Spilaio where it is mentioned that the abbot was Methodios.
Cyriacus of Ancona visited
Arta in 1436 and informs us that he attended the liturgy held in the church of Panagia and was hosted in the monastery. The Monastery of Koronisia had a large property mainly on the coasts of
Aetolia-Acarnania and fish farms in Kalogeriko Artas, while it was particularly known for the eel farms it had in the Ambracian gulf, because of which the monks received threats from the inhabitants of Vonitsa. A letter of Patriarch
Jeremias I, in 1530, to the bishop of Vonitsa, in which he ordered them not to harass the monks of Koronisia, is mentioned. In 1603, Sultan
Mehmed III sent a decree to the governor of the
Karleli sanjak and the
kadis of Arta, Agia Mavra and Vonitsa and requested that the military authorities stop disturbing the monks and respect the property of the monastery at Myrtari in
Vonitsa. In 1670 it was radically renovated by the
hieromonk Eugene of , who went to the monastery of Koronisia and built the cells of the monastery and gathered the monks. In 1860, the Ottoman government built, for the protection of the fish farms of the monastery, a small fortress, the "koulia" of Koronisia. In 1918 the Monastery of Koronisia ceased to function as a monastery and became a
metochion of the monastery of Prophet Elijah in
Iliovounia and was converted into a parish church. In 1969, by ministerial decision, the temple was declared a preserved monument. In 1969 a ministerial decree made the monastery a listed site. ==References==
