Pingyao still retains its city layout from the Ming and Qing dynasties, conforming to a typical bagua pattern. More than 300 sites in or near the city have ancient ruins. Preserved Ming- and Qing-style residences number close to 4,000. The streets and storefronts still largely retain their historical appearance.
The city walls of Pingyao were constructed in the 3rd year of the Hongwu Emperor (1370).
