Olı Klüçä

Olı Klüçä (also spelled Olı Kilise) is a historic Byzantine-era church located near the village of Yapraklı in the Güzelyurt district of Aksaray Province, Turkey. The name, translating roughly to "Great Church" or "Grand Church," indicates its former significance within the region.

While the exact date of construction is debated, Olı Klüçä is generally believed to have been built during the Byzantine period, likely between the 6th and 11th centuries AD. The architecture reflects typical Byzantine church design, featuring a basilica plan with a central nave and side aisles.

Significant damage over time, caused by earthquakes and weathering, has left the church in a partially ruined state. However, substantial portions of the walls and apse remain standing, showcasing the original stonework and architectural details. Although the interior frescoes are mostly lost, traces of painted decoration can still be observed in some areas.

Olı Klüçä stands as an important historical and archaeological site, providing insight into the Byzantine presence in Cappadocia. Its location, somewhat remote, contributes to a sense of its past importance and the religious life of the region during the Byzantine era. Conservation efforts are ongoing to preserve the remaining structure for future generations.
