XI'AN, Nov. 6 (Xinhua) -- Archeologists recently found three 2,000-year-old luxury baths in northwest China's city of Xi'an, the local heritage department said Monday.

Three ancient city sites, dating back to different dynasties, were discovered by a team at an archeological site at the ancient city of Liyang, according to Liu Rui, a researcher on the team.

Liyang, a former capital in the Qin and Han dynasties, is now located at Yanliang district of Xi'an, capital of Shaanxi Province.

Three baths and a fireplace have been excavated at one site. The baths have been built with beautiful tiles and bricks, with sewage outflows.

"The shape, structure and size of the baths were very similar to the baths in the imperial palace of Xianyang, capital during the Qin Dynasty," Liu said. "These baths could be the earliest baths discovered in China."

The 2013 excavation of ancient Liyang was conducted by the Chinese Academy of Social Sciences Institute of Archaeology and the city's cultural relics protection and archeology institute.
