The cathedral, 35 meters wide, 78.69 meters long, and its twin towers 58.5 meters high is the largest Roman Catholic church in the Gothic style in China and Southeast Asia. It is sometimes referred to as 'Notre-Dame de Paris' in the East. Sacred Heart Cathedral, or Stone House, a Roman Catholic cathedral, is one of the oldest churches in Guangzhou and the largest of its kind in Southern China. Located on the north bank of the Pearl River, the church stands in the heart of the busy old town.
The cathedral was consecrated in 1888 after 25 years of construction. The construction of the cathedral turned out to be very challenging. None of the Chinese workers at that time had seen a western cathedral before, let alone built one. It was also tough for them to communicate with the French clergy who commissioned the building.
