With over a billion members and 400,000 priests, the Catholic Church is one of the largest organizations in the world. And with a history reaching back over 2,000 years, it is also one of the oldest.

This site collects and curates information about people, places, regions, events, organizations, and literature of the Catholic Church (both Latin and Eastern Rites). As often as possible, we obtain information from official Church sources such as Vatican press releases and Diocesan announcements.

By gathering Catholic information into a comprehensive database, we hope to facilitate the study of the rich history of the Church, to foster the development of technical tools such as apps and visualizations, and to bring people to a deeper understanding of Catholicism.
