This museum focuses on the architecture and stained glass of European Gothic cathedrals from the 12th to 14th centuries. By emphasizing structural innovations such as rib vaults, pointed arches, and flying buttresses. Alongside these innovations are expansive, richly colored stained-glass windows. The exhibit explores how these cathedrals transformed solid stone and glass into luminous, soaring sacred space. The resulting architecture was not only functional but also symbolic: light filtered through the glass was understood as a divine presence. At the same time, vertical lines and vaulted heights guided the eye upward, signaling a spiritual ascent. Through visual examples and descriptive labels, the museum demonstrates how Gothic design fused engineering ingenuity with spiritual symbolism to create immersive, transcendent interiors.
