Lý Nhân Tông
Cham art also spread far across the Red River Delta, where many Vietnamese Buddhist temples hosted Cham-style statues of dragons, lions, "nāgá," "makara", kinnari, Brahma and Hamsa dated back to the 11th–13th century. Thousand of bricks inscribed with Cham script indicate that a multitude of Vietnamese temples and holy sites were built based on the Cham architecture style. A Buddhist stone stupa of Dạm tempe in Bắc Ninh Province, built by Vietnamese king Lý Nhân Tông in 1086, is a representation of a lingam and its yoni (a Hindu-Cham symbol of fertility and the power of creation).
