The Erqi Memorial Tower, situated in the Erqi Square in downtown Zhengzhou of Henan Province, was built on September 29, 1971, to commemorate the setting up of Workers' Union of Beijing-Hankou Railway as well as the whole-line Communist-led strike of rail workers held at Zhengzhou Pule Park (today's Erqi Memorial Hall) on February 7, 1923.

The Erqi Memorial Tower has altogether 14 storeys, totaling 63 meters in height, and is also called Twin Tower, because its body is made up of two connected quinquangular parts. A winding stair inside the tower brings you up to the top floor, where you can get a bird's-eye view of the whole city of Zhengzhou.

The tower looks solemn and imposing, which has been one of Zhengzhou's historical spots.
