Yongzuo Temple, popularly the Twin Pagoda Temple, lies southeast of the city of Taiyuan and was built in the Ming. Its two thirteen-storey octagonal brick pagodas stand side by side, more than fifty metres tall, and are the emblem of Taiyuan. The Mahavira Hall is built entirely of brick vaults without a single timber beam and is known as a beamless hall. Liang Sicheng mentions the twin pagodas and the vaulted beamless hall in his book.
