The area of the Chinese city site is a maritime trading network that entered North Sumatra via the Sumatra Northeast coastline in the 11th to 14th centuries. The Chinese City Heritage site owned by North Sumatra located in Paya Pasir Village, Medan Marelan Subdistrict. Information on the condition and subsurface shape of the site is needed to reveal the existence of the site so that it is easy to excavate and does not damage the surrounding soil. The study aimed to analyze the distribution of Chinese cities below the surface. The research was carried out by using the 6-track Wenner-Schlumberger geoelectric method. Each track used 16 electrodes with an electrode distance of 5 m. The data was processed using Res2DinV and Surfer software. Alluvial layers dominated the results obtained from the subsurface structure. The resistivity of the northern part of the site has a low anomaly starting at 1.25 meters which were the uppermost layer dominated by shallow brackish groundwater that has been intruded. The Chinese city site in the form of temples was found in the southern part at a depth of 1.25 meters to 3.88 meters marked with red bricks filled with water with resistivity 28.9-56.7 Ωm and findings of artifacts around the research location.
