Key archaeological findings were recently made at nearly 3,000-year-old city ruins on the outskirts of Beijing, the city's cultural heritage administration announced on Thursday.

In the northwest of the Liulihe site in Fangshan district, a complex of architectural remains with a clear layout was newly unveiled in an ongoing excavation, according to Wang Jing from the Beijing Archaeological Research Institute, who is also a leading archaeologist working on the site.

Based on her team's research, the constructions had been built using rammed earth. Each layer of earth was 8-to-12-centimeters high.
