Saint Stephen Diocesan Center

Saint Stephen Diocesan Center, formerly Saint Stephen Seminary, was acquired by the Diocese of Honolulu in 1946 and is located at the former 22 acre estate of Harold K.L. Castle nestled within the Ko'olau Mountain Range. The Castle Mansion was built in 1927 and currently serves as the residence of the bishop of Honolulu. After the seminary's closure, the Cullinan Building was transformed into a diocesan center housing various offices of the diocesan curia.
