Foundation of the Monastery
In Arta, Theodora founded a women's monastery originally dedicated to Saint George. Following her death the community took her own name, becoming known as the Monastery of Saint Theodora, and she came to be honored as a patron of the city.
The katholikon associated with her veneration is a three-aisled basilica built over the ruins of an older structure during the reign of Michael II Komnenos Doukas, Despot of Epirus. It is counted among the notable Byzantine churches of Arta.
