History
The Basilica of the Catechumens is a medieval Orthodox church beneath Servia Fortress in northwestern Servia, Greece. Built around 1000 on the foundations of an early Christian church, it is also known as the Church of Saint Demetrius and the Forty Gates. Saint Demetrius was an early Christian martyr venerated especially in Eastern Orthodox Christianity.
The church served as the cathedral of the Diocese of Servia and is affiliated with the Ecumenical Patriarchate, the Orthodox Church’s patriarchal institution based in Constantinople, now Istanbul, and the Servia deanery. Alterations made between the 12th and 16th centuries changed the building over time. The church is no longer in use.
Remains
Now in ruins, the church has a three-aisled layout with a raised central nave. Its building and painted decoration preserve evidence of successive phases.
Church remains
Plan and construction
The first phase was a single-nave building with a wooden gabled roof. Its main worship space, or naos, connected to the side areas through an opening divided into three arches. The later basilica has three aisles, an entrance vestibule called a narthex, and a raised central nave with a clerestory, an elevated section that admits light. Walls separating the aisles contain four arched openings.
Wall paintings
The church’s wall paintings form three layers. The earliest belongs to the building’s first phase. A second layer dates to the 13th century, when Bishop Michael led the diocese. A third layer may date to the 15th or 16th century; excavations between 1995 and 2000 uncovered fragments of it.
