A nunciature is a diplomatic mission led by a representative of the Vatican City, known as a nuncio. This position is similar to that of an ambassador, and the nunciature serves as the Vatican's official diplomatic office in a foreign country. Nuncios are responsible for maintaining relations between the Holy See and the host nation, promoting the interests of the Catholic Church. Nunciatures play a crucial role in international diplomacy, particularly in matters involving religious and humanitarian issues. They also facilitate communication between the Vatican and local bishops, helping to coordinate church activities and address concerns within the Catholic Church in that region.
