Introduction to the Han Dynasty beacon tower ruins: The beacon tower ruins are located on the hills of the Qipanshan Development Zone in Shenyang City. They have a history of more than 3,000 years. From a distance, they look like a "mound" covered with grass. A large number of typical corded tiles and pottery shards from the Warring States Period were found around the four "mounds", which are of great significance to the study of the history of the Great Wall of the Warring States, Qin and Han Dynasties in the Shenyang area.
