The Twin Pagoda Temple officially known as Yongzuo Temple  of Taiyuan, Shanxi province, China, is a temple containing two pagodas dating from the Ming dynasty.

The East pagoda was built in 1597, and the West one in 1612. In charge of the pagoda’s construction was a high ranking monk, named Fodeng. By the 20th century, deterioration since construction had caused the East pagoda to slant from its center of gravity by 2.87 meters. In 1995, experts set about trying to correct the slant. They removed earth from underneath the pagoda and successfully corrected the pagoda's tilt.

The pagodas are the tallest set of twin pagodas in China. They are both eight-cornered, with the lowest floor being comparatively taller than the rest, the size of the upper floors progressively decreasing. The West Pagoda is 54.78 meters tall, with the lowest floor’s circumference being 4.16 meters. The pagoda’s eaves are painted with emerald green glaze. The East Pagoda is 53.3 meters high, and the lowest floor’s circumference is 4.36 meters. On top of the East pagoda are three magic gourds, with the upper two parts being made of copper.
