Phat Diem stone church, Ninh Binh, Vietnam.
The church was built between 1875 and 1898 in the province’s Kim Son District by the Vietnamese priest Tran Luc known as Father Sau, who designed the church without any training in architecture or painting. The most remarkable feature of the Cathedral is that it is made with marble and granite. Therefore, it is also known as the Stone Church. The church also includes a complex including several artificial lakes, churches, and artificial caves.
