Introduction
On 11 March 843 AD, Empress Theodora issued the decree that restored icon veneration across the Byzantine Empire, ending 117 years of intermittent iconoclasm. The event — still commemorated annually as the Triumph of Orthodoxy — reshaped the visual landscape of every church in Thessaloniki.
The gold-ground mosaics that visitors photograph today in the Rotunda and the Acheiropoietos basilica exist in part because a woman made a decision that male emperors before her had refused to make. Theodora is the most documented of many Byzantine women whose influence is embedded in the city’s built environment.
Thessaloniki’s position as the empire’s second city made it a natural destination for aristocratic patronage, monastic foundation and saint veneration — much of it driven by women whose names appear in faded donor inscriptions, hagiographic texts and the Museum of Byzantine Culture’s collection of more than 3,000 objects related to daily life.
Byzantine women: Two saints, two centuries apart, both still present in the city

Saint Anysia: the earliest female martyr in the city’s Christian record
Anysia of Thessaloniki died during the persecution of Christians under Emperor Maximian, most likely around 298 AD. According to hagiographic sources compiled by the 10th-century bishop Symeon Metaphrastes, she was killed at the city’s gates by a Roman soldier after refusing to deny her faith. Her feast day, 30 December, has been observed continuously in the Eastern Orthodox calendar since late antiquity.
The Church of Saint Anysia near Thessaloniki’s Ano Poli district is a small 19th-century structure built on a site associated with her veneration since at least the Byzantine middle period. It functions as an active parish, not a heritage site — which means the liturgical calendar, not a tourism board, determines when the doors open.
For a figure whose historical documentation is thin, the continuity of local devotion over seventeen centuries is itself a form of evidence.
Saint Theodora: relics in their original location since the 10th century

Theodora of Thessaloniki (812–892 AD) entered the Monastery of the Holy Apostles around 830 AD, bringing her young daughter with her. She lived as a monastic for roughly six decades, during which she reportedly continued the private veneration of icons throughout the second iconoclastic period (815–843 AD).
Her biography, written by the monk Gregory within a generation of her death, is one of the few surviving hagiographies of a Byzantine woman written close to the subject’s lifetime.
Her relics were transferred to the Church of Saint Theodora on Agias Sofias Street, where they have remained since the 10th century — an unusually stable history for Byzantine relics, which were frequently moved, sold or lost during the Ottoman period. The church continues to hold regular liturgy. Visitors who arrive outside service hours will find the door locked, which is worth checking before making a dedicated trip.
Empress Theodora and the decision that changed the city’s walls
Empress Theodora (815–867 AD), wife of Emperor Theophilos, served as regent for her son Michael III from 842 until 856 AD. During the first year of her regency, she convened a council in Constantinople that formally condemned iconoclasm and reinstated the veneration of sacred images. The decree was issued on the first Sunday of Lent in 843 — a date that became the Feast of Orthodoxy, observed annually to this day in every Orthodox church worldwide.
The practical consequence in Thessaloniki was immediate. Churches that had been stripped of figural decoration during the iconoclastic period were repainted. The mosaic programme of the Rotunda, parts of which date to the 5th century but were restored and extended in the 9th, reflects this post-iconoclast revival.
Theodora was never based in Thessaloniki and has no tomb there, but the city’s visual character — the gold-ground figurative art that defines it — is inseparable from her political intervention.
Aristocratic donors: the Byzantine women behind Vlatadon and other foundations

The Monastery of Vlatadon, founded in the mid-14th century on the site of an earlier Byzantine structure in Ano Poli, is traditionally associated with the patronage of Anna Palaiologina, wife of the Byzantine governor of Thessaloniki.
The monastery is one of the few Byzantine monastic foundations in the city to have survived continuously through the Ottoman period to the present. It currently functions as the Patriarchal Institute for Patristic Studies. The pattern of aristocratic female patronage that Vlatadon represents was not unusual.
Donor portraits in churches throughout the city — women shown holding miniature church models or scrolls of dedication — document a network of private patronage that sustained Byzantine religious infrastructure across generations. These images are not symbolic. They record legal acts: the donation of land, the funding of construction, the endowment of clergy. The Byzantine women depicted were the architects of record.
Where to find this history in Thessaloniki today
The Museum of Byzantine Culture (Stratou 2, Thessaloniki) holds the most concentrated evidence of women’s daily life from the Byzantine period. Rooms 3 and 4 contain jewelry, textiles, household objects and tomb goods that document female experience beyond the hagiographic record — items connected to childbirth, domestic economy and personal devotion.
The museum is open Tuesday through Sunday; entry is €8, reduced €4. Signage is in Greek and English. The Church of Saint Theodora (Agias Sofias Street, near Arch of Galerius) houses the saint’s relics in the original location.
The Panagia Acheiropoietos (Agiou Dimitriou Street), dating to the 5th century, contains the earliest intact mosaic programme in the city and one of the oldest surviving representations of the Virgin in a major ecclesiastical context. Both are active churches; photography during services is not permitted.
The Monastery of Vlatadon (Eptapyrgiou Street, Ano Poli) is accessible to visitors during designated hours. The frescoes in the katholikon include donor portraits from the 14th and 15th centuries. The walk from the city centre takes approximately 25 minutes on foot through the upper Byzantine walls district.
