St. Joseph Cathedral is a late-19th century Catholic church built during the treaty port era, when Wuhu was opened to foreign residence and commerce. The building follows a simplified Gothic Revival style common in missionary construction of the period — pointed arches, a western facade tower, and a nave that is modest by European standards but was ambitious for its context. The exterior brickwork and the proportions of the tower are the most architecturally notable elements.
The cathedral remains an active parish church with a congregation that includes both descendants of historical converts and newer Catholic families. It is open to visitors outside service times, and the interior preserves the original altar and some of the original woodwork. For those interested in the history of Christianity in China, or in the physical legacy of the treaty port era in the interior provinces, it is a genuinely interesting stop on the way to or from Mirror Lake.
