Sanyuan Gulong Bridge

Sanyuan Gulong Bridge, commonly known as "Three Eyes Bridge", was built in the 19th year of Wanli in the Ming Dynasty (1591). . The architectural design of the bridge adopts the form of a three-hole arch bridge. The bridge is 110 meters long and 11 meters wide. The bridge body is made of stone bars and iron clamps. It is one of the well-preserved ancient stone arch bridges in Shaanxi Province. "Water passes through the jasper ring, and people walk on the back of the blue dragon", which is an image depiction of the ancient dragon bridge. On the outside of the stone fence, there are three dragon heads and three tails, with the head east and the west tail. The two north and south slopes of Longqiao are S-shaped, and there were gates facing north and south at the Potou. The dragon head and tail on the bridge are connected with the water channel on the bridge surface. On rainy days, the water on the bridge area is sprayed from the head and tail of the dragon, pouring straight into the river, and the scene is spectacular. The bridge body of the Dragon Bridge is all built with bluestone strips, and the structure is solid, and it still stands stably after more than 200 years.
