Intricate and vibrant Byzantine-style frescoes cover every inch of the walls and ceiling inside a sacred chapel at the Monastery of Roussanou in Meteora, Greece. Richly detailed iconography depicts solemn biblical scenes, haloed saints, and angels, wrapping around a small, open wooden window that lets in soft natural light. Beside a beautifully patterned stone floor, an ornate golden iconostasis screen stands elegantly on the right, partitioning the sanctuary's spiritual heart.
