 The later Song Dynasty also built cast iron pagodas, exploiting its ability to be both structural and to be cast in any shape, such as in imitation of the timber and tiles of a standard pagoda.The 22m Iron Pagoda at the Yuquan Temple (Jade Springs Temple), Dangyang, Hubei, was built during the Song Dynasty in 1061, and is the most outstanding example to survive.Cast iron pagodas were then superseded by even more elaborate bronze ones, but cast iron continued to be used for decorative items such as bowls and statues.
