The old county seat of Qushan Town in Beichuan can be viewed from a designated observation pathway along its perimeter. The town was largely destroyed by the 7.9-magnitude earthquake of 12 May 2008, when the surrounding mountain slopes collapsed onto the valley-floor settlement and the buildings themselves — many constructed to substandard specifications — pancaked. Rather than rebuild, the government sealed the town and preserved the ruins as they stood on the day of the earthquake.
The effect is of a suddenly stopped place. Collapsed apartment blocks, buried streets, toppled water towers, and broken road surfaces remain exactly as they were in May 2008 — trees have grown through and around some of the ruins in the sixteen years since, which adds to rather than diminishes the sense of arrested time. Beichuan Middle School, where hundreds of students died in classroom buildings that collapsed while nearby structures survived, is the most emotionally concentrated part of the site. The scale of the destruction becomes apparent gradually as you walk the observation path.
