The image showcases the old town of Bern, the capital of Switzerland, with red - tiled roofs covering medieval - style buildings, Gothic church spires and clock towers dotted among them, and bridges by the Aare River interwoven with green trees. The old town of Bern was listed as a UNESCO World Heritage Site in 1983. It preserves a large number of buildings from the 15th to 18th centuries, and the integration of red - tiled roofs, stone - paved streets, and natural landscapes creates a tranquil and primitive atmosphere of a European ancient city, which is a microcosm of Swiss history and culture.
