The Zhenhuai Building is a substantial wooden structure dating to the Song dynasty, now serving as a city museum with exhibits on Huai'an's two-thousand-year history as a canal and administrative centre. The building itself is the attraction as much as the collection: a large multi-storey timber structure in good repair, occupying its hilltop site with authority. Views from the upper floors take in the canal district and give a sense of the city's topography.
The museum's collections cover Huaiyang cuisine culture, Grand Canal history, and the city's role as a key transfer point in the imperial grain transport system. The exhibits are in Chinese, but the building is sufficiently impressive that the visit works even without language access. The site is worth an hour for the architecture and the views.
