The Tomb of Zhang Heng is situated in Shiqiao Town, 25 kilometers north of Nanyang County, Nanyang City, Henan Province.

Born in Xi'e (today's Nanyang) in Henan Province, Zhang Heng (78-139) was a famous scientist and intellectual of the Eastern Han Dynasty (25-220). As a master of mathematics and astronomy, Zhang constructed a rotating celestial globe in 117 for observing the skies. In 132, he invented the first seismometer for measuring earthquakes and explained the changes of the four seasons, including the waxing and waning of the moon. Zhang also produced many literary works. Zhang was buried in his hometown, Nanyang.

Encircled by a passageway and walls, Zhang's tomb yard covers a land area of over 5,000 square meters and contains a coffin chamber 8 meters high and 79 meters in diameter. There are pine trees in the tomb yard and three steles in front the tomb. The steles record Zhang's achievements and the tomb's discovery.
