Vize Small Hagia Sophia Mosque (Gazi Süleyman Paşa Camii)

In the Kale Neighborhood of Vize District, Kırklareli Province, the Vize Küçük Ayasofya Camii, situated between the inner and outer walls, is an original structure that bears witness to both Byzantine and Ottoman architectural traditions. It is also known as the Gazi Süleyman Paşa Camii. Originally constructed in the 6th century as a church during the reign of the Eastern Roman (Byzantine) Emperor Justinian I, the building was converted into a mosque in the second half of the 15th century and adopted the name Gazi Süleyman Paşa Camii. Today, the structure remains open for worship and represents a multilayered cultural heritage that sheds light on the religious and architectural history of the region.

Architectural Features

The building has a near-square rectangular plan with three apses. The central dome rests on a sixteen-sided drum, and the interior space is divided into three sections by four large piers with diameters of 1.30 to 1.40 meters that support the dome, along with columns positioned between them. The capitals of the columns are carved in the Corinthian order, enhancing the aesthetic value of the structure. Although the mosaic decorations have been lost over time, existing documents and architectural remnants suggest similarities with the mosaics found in the Hagia Sophia and Hagia Irene churches.

On the western facade, there was once a narthex featuring three marble portals in Byzantine style. The exterior walls, constructed using a combination of stone and brick, reflect the composite architectural techniques characteristic of late Byzantine construction. The dome’s covering system consists of cross vaults and barrel vaults. In addition to the minbar, which no longer exists, the mihrab is a later addition made of concrete.

Historical Development

Although no definitive inscription or document confirms the exact construction date, architectural analysis places the structure in the 6th century. After the Middle Byzantine period, it is believed that the church assumed its current architectural form during the 13th and 14th centuries. The building’s ground plan follows the basilica type, while its roof system and cruciform layout exhibit characteristics of the Greek cross plan. This dual planning approach represents an original feature of late Byzantine church architecture.

From the exterior, the building presents a cruciform appearance, and a cemetery is located on its western facade. Given that Vize was one of the last major centers of the Byzantine Empire in Thrace, it is likely that this structure played an important religious and administrative role. Some regional sources suggest the building may have functioned as a psychoposlon—a place for the care of the dead—but this claim has not yet been conclusively verified.

Ottoman Period and Conversion into a Mosque

Following the definitive incorporation of the region into Ottoman rule after 1453, the Küçük Ayasofya Church was converted into a mosque. However, historical sources provide no clear information regarding which Süleyman Paşa oversaw the conversion or to whom the name was dedicated. The common Ottoman practice of converting conquered churches into mosques is clearly evident in this structure. This transformation served both to establish the region’s new religious identity and to meet the worship needs of the established Muslim community.

Recent Restoration and Conservation Efforts

Over time, the building became partially buried beneath soil levels, leading to moisture-related damage. During World War I, interventions by Russian and Bulgarian forces in the region resulted in the mosque being temporarily reverted to use as a church, causing significant damage to its architectural elements. Many artistic artifacts were lost during this period.

The first systematic conservation effort was undertaken by the General Directorate of Foundations between 1979 and 1984. The mosque underwent further restoration in 1995 and, in 1997, was subjected to partial cleaning and maintenance in collaboration between the Archaeology and Art History Department of Trakya University and the Kırklareli Museum. Finally, in 2007, the General Directorate of Foundations carried out a comprehensive restoration, returning the structure to its original form and achieving its present appearance.

Architectural Value and Significance

The Vize Küçük Ayasofya Camii (Gazi Süleyman Paşa) is one of the most important cultural heritage structures in the region, distinguished by its hybrid architecture reflecting both Byzantine and Ottoman influences, its dual plan layout, and its unique use of materials. Evaluated in relation to the Hagia Sophia and Hagia Irene churches in Istanbul, this building is not only a local landmark but also a regional example that reflects broader characteristics of Byzantine church architecture. Its continued use for worship today further distinguishes it as a living cultural entity.
