From April 2011 to November 2012,a joint archaeological team from the Shaanxi Academy of Archaeology and the Han-Dynasty Yangling Museum conducted an excavation at the East Gate-Tower of the imperial mausoleum park.The excavation covered an area of 700 square meters,unearthing 234 artifacts or sets of artifacts,with tile-ends predominating among the various kinds discovered.This excavation clarified the structure of the Han-Dynasty Yangling Mausoleum park and the construction method of the East Gate-Tower.These findings will aid further studies on the evolution of the ritual system related to the gate tower and the reasons for its eventual abandonment.Additionally,this excavation provides valuable reference for the sustainable protection,research,exhibition,and utilization of the site.
