St Mary's Cathedral in the Mariapuram neighbourhood is the seat of the Roman Catholic Diocese of Kadapa and one of the more architecturally striking churches in Andhra Pradesh. The Gothic façade — twin spires, pointed-arch windows, carved stone — would not look out of place in southern Europe and is unusual for inland south India. The interior is high-vaulted and well kept; daylight through the side windows is the right time to see it.
The cathedral opens around 9 a.m. and is open to visitors throughout the day outside service times. Modest dress and quiet voices. Address: Mariapuram, Kadapa.
