The Dui Yue Gate (兌悅門), built in 1836, commonly known as the Coral Stone Gate (咾咕石城門), is located on Xinyi Street (信義街), and is the only city gate in the district still in use. Xinyi Street used to be called Coral Stone Street, as the area outside the gate was full of waterways where boats used coral stones as ballast.Tainan once had 14 city gates, and while this gate is no longer as important as it once was, it is the only gate that people still walk through. The traditional city gate contrasts with Xinyi Street's new trendy boutiques, highlighting the juxtaposition of new and old in Tainan.
