Shikumen is a traditional architectural style found in Shanghai, China. It combines elements of Western and Chinese design, featuring stone walls, wooden doors, and tiled roofs. These buildings typically have a narrow entrance leading to a courtyard, which serves as a communal space for residents. Originally built in the late 19th and early 20th centuries, Shikumen houses were designed to accommodate the growing urban population. Today, many of these structures are preserved as cultural heritage sites, reflecting the historical blend of cultures in Shanghai and offering insight into the city's past.
