The Selime Monastery, often referred to as Selime Cathedral or Castle, is a monumental rock-cut structure located at the northern end of the Ihlara Valley in Cappadocia. Dating back to the 8th or 9th century, it holds the distinction of being the largest rock-cut monastic complex in the region.
Carved directly into the volcanic tuff cliffs, the complex served a dual purpose: as a vibrant religious center and as a formidable fortress against invaders during periods of conflict. It was a place of worship, a theological school where clergymen were trained, and featured a massive, cathedral-sized church with a cross-shaped plan and towering domes.
Inside, visitors can still observe faded yet significant Byzantine frescoes depicting scenes like the Ascension of Christ. The expansive structure also includes monk cells, a large communal kitchen, stables, and defensive features like hidden passageways, indicating a self-sufficient community. Its commanding position overlooking the Güllüdere Valley made it a strategic stronghold. Selime Monastery is a highlight for those concluding a hike through the scenic Ihlara Valley.
