Padri-Ki-Haveli ("Mansion of Padre"), also known as the Visitation of the blessed Virgin Mary, is the oldest church in Bihar. When Roman Catholics arrived in Bihar, they built a small church in 1713 at a place now known as Padri-ki-Haveli. The current church was re-designed by a Venetian architect in 1772. He came from Kolkata to design the church. The foundation stone of this church has a dimension of 70 feet of length, 40 feet of width and 50 feet of height. Today, the monument stands as an architectural wonder with intricate details present in few churches in India.
